Glossy blue, printed on one side & stamped on reverse: “Art is:”.
"A show called 'Definitions of Art' will be held at OTHER BOOKS AND SO Herengracht 227 Amsterdam from
1st March to 26th March 1977.
Everybody is invited to participate, regardless of profession, sex, age, etc.
Just write your definition (of what art is) on the back of this card, put it in an envelope, and send it back to Other Books and So. The show will consist of all the cards received, and a selective catalogue will be published.
The original idea for this show is by H. W. Kalkmann."
Near fine, but for light wear to edges and slight rubbing to silver letters.
