"The eyes were always (presented) in sets of two: I photographed the dealer, and the dealer photographed me. Then only exception (as I remember) was the very first one, which was not a postcard but an ad in some magazine; I forget which magazine. Though the postcards always came in sets of two, the format varied: sometimes they were attached to each other with perforations, sometimes they were separate. They were mostly postcard-sizes, although one set was long and thin. I seem to remember one set on A4 paper. They always came in envelopes; often the exhibition details (dates, etc.) were printed on the outside of the envelope, rather than on the postcards. I preferred the separation of content from information, making the information external" Joel Fisher
