I have about 72 prints from the New York Graphical Society from the 70-80's and I put them on ebay and nobody baught them. I even asked the same price they were in 1970-80. Some of them were numbered and signed. I had several people ask me if I wanted to buy theirs though
Ebay is lousy market for contemporary photography. Deco, Nouveau, Hurrell, Clarence Bull, anything with the slightest nostalgic or classic association can do incredibly well, but not contemporary...unless it's framed and under $35.00. An original print of Fay Wray in her famous brassiere-revealing King Kong pose went for $8,500 yesterday, about 80 times my bid.
Try some of the big photo galleries, they might at least list your stuff.
