Pfft – there is more value in the conceptual artistic merit of the ‘Mystery roll’.

Put it on ebay – with the description:

FOR SALE – 1 x roll of exposed Kodachrome, taken by a mystery photographer.
Who was the photographer? Was it your next door neighbours grandfather, or was it shot by the dude who took ‘Afghan Girl’…..
What are the images? Do we have pictures of Aunt Bettie’s cat, or do we have the evidence that it was the person on the Grassy knoll
Revel in the wonder. You may just have the most important photographs in the world sitting on your shelf.

I think if we start at $1000/roll, surely we could get at least $500,000?

(kinda like selling pieces of the real cross, hey…)
