Money Art by Sarala Kron
Jeffrey Errick of Stuff by Wackystuff blog has an extensive collection of fantastic retro art, but it was his Money Mail-Art Call that got our attention. Jeffrey asks artists to mail him "money" art (not real currency, money is just the theme) that he then posts on his blog. If you send him your money art, he'll send you something back!
This one above is by Sarala Kron, USA:
Since she is a doctor, Sarala sent us a Health Care Dollar,
complete with annuity chart and cigarette warning label.
It arrived in a Monopoly money envelope.
