...The guy on the left just lifts the right corner of his mouth very little, but his whole face smiles.
Just two photographs of a moment in time, but interesting differences.

I looked at the guy on the right and thought: what an unusual expression. Later I realized, he's actually trying to smile!
In the Netherlands we have a saying: 'he laughs like a farmer with a tootache'.
Either that, or the poor guy could have constipation problems. If I am right, I hope for him, and his employees, he gets well soon.

My last guess, honestly. Could it be a thing for collecting toll money for boats? They hang or throw it from a bridge on a rope, so someone on the boat can put money in it. Could have been a sign with the price under the nail.

Put a weight in it and whatever you hit (dust out of a carpet, or meat or whatever) gets hit with more power because of the outward force.

I don't know, could also be used for spanking while shaking a cocktail at the same time. Those dominatrixes can be very efficient.

Or you use it to pick fruits from bushes with thorns. You need one hand for picking, and with this tool you keep the thorns away and have a container to collect the fruit (or maybe insects or something you don't like near your body too much)

Maybe it's for catching or keeping leeches, or snails or something. You let it float with the container in the water. And pull it behind the boat if you go. Looks like there was a lid once.

It's for collecting shit. First you hit the shit out of something, and then you put it in the container.

Only 2 comments? What's happening? Maybe, just like me, many fans are afraid of influencing the jury of the Caption-contests?
From me, and all those people: congratulations with 1000 unique and poetic, original, one of a kind cartoons.

@HollywoodBob: a camera on every street-corner is the same as a police-officer on every corner. Actually worse, because camera images are kept. There is no difference with a police-state.
You are expected to behave like everybody else. Spontaneous behavior is suspicious. Act like the crowd. Whatever you do, do not stand out.
Do not jump in the air if you're very happy. Don't dance on imaginary music with that girl you haven't seen for a while. Do not stop on the street and play music, or sit on the curb with a friend. Don't sit on the bonnet of your car with a friend. Do not stand on a bridge and daydream while watching the water or the birds. Do not walk playful touching every second brick or lamppost. Do not act out movie scenes when you leave the movie theatre. Do not offer anything to people, no flowers, no chewing gum, no money. Don't walk on your hands. Don't juggle. Don't tie your shoelaces in public. Do not argue or talk too loud in your mobile phone. Do not talk with your hands too much. Don't be too happy.
If you do, you will be watched closely. Your face will be registered and your identity checked. You are potentially disturbing the peace. Possibly drunk or on drugs. Next time a microphone on the camera will record your conversations. Also your behavior on the internet and your telephone conversations will be monitored.
And it will all happen automatic, by computer.
Your big brother is looking after you. He knows what is best for you. He watches after your safety. He's your elder brother and he loves you. He knows you are passionate about your freedom, and you get carried away sometimes. Trust him. No need to get paranoid. Don't worry and sleep. Big Brother is watching you.

It's a gun you use when you are out of ammunition. You stick the two barrels up the nose of your attacker and open and close the gun like you are clapping your hands.

...or maybe miss cellania just meant that.

I can't believe nobody said nutcracker already. Like for walnuts.

Forget the jack. It's a paperweight, to be used inside a bookcase, for extra pressure.
Of course also useable for pressure while glueing things, or leveling the shelves when constructing a bookcase.

In many countries and professions they need too many men to screw in a light-bulb. With this device two men can do the job. A wonderful piece of engineering.

My compliments to the teacher and his students.
I enjoyed the site very much. It's like a work of art, a tribute to the American Indians. No information, no advertisements, no distractions, just the amazing photographs and the whispers from the past.
There is a rhythm in the layout and the colors. Simple, respectful and close to the earth, just like the people.
Many websites look like advertising brochures nowadays. But sites like this have an extra, deeper quality. Not too long, not too short, perfectly balanced, a monument for the people represented. I really wish there were more of such sites around.
