I hope you find the other half. Don't give up looking. I searched for half of a very rare black and white glossy photograph. The photo was of a Columbia Pictures banquet attended by famous actors of the 30's and 40's. I purchased my half in 1989 then in 2007 I found the other half on ebay. It was incredible. I later sold the picture and it has since been published in a film history book.
That is an awesome story hri_2008. I will keep looking, and like yours, eventually it will come up(I hope)! I could not leave it behind just because it was missing the other half!(lol)
