Aart van Barneveld posing in front of Stempelplaats.
Stempelplaats was a mail art gallery in the shop of Posthumus rubber stamp makers in the St. Luciensteeg in amsterdam. Photo by @Ginny_Lloyd for Umbrella Magazine in 1982. Found the photo on Ginny's Blog where she republished the Umbrella article about the Mail Art scene in europe.
