Hey, Mark, is that you, to the right? If so, we're sorry for the snark, and also, SFist reader crow soup has a picture of you in his possession that you might want back.
Here's what crow soup had to say about this lovely find. Be sure to check out his found set on Flickr!
I just dug the picture out of it's place and according to my notes I picked it up on August 21, 1996 somewhere around 8th and Howard. The inscription on the back says, in old looping cursive, "St. Francis Hotel - Mark (illegible last name) & Tracey _______ - Senior Prom - May 5th, 1978." I wish Tracey was in the picture, I'm sure her dress was the bomb.
