Although "reality TV" is trying to convince me otherwise, I don't think poking around stores hoping to find some hidden treasure is exactly a hobby. That being said, I do find it interesting, and occasionally I do find something hobby related.
One such find, years ago, was a box of hockey cards. As a kid, I never had the financial ability to buy a whole box of hockey cards. I bought them one pack at a time, carefully sifting through them while trying desperately to make that cardboard like piece of gum soft. Sometimes I bought three packs in a day, going back to the store for each one. A whole box was unthinkable.
This treasure find, in a dingy discount store in an even dingier mall, involved a box of Original Six hockey cards. The idea was to release a series of hockey cards, some in black and white, of my father's hockey heroes. They probably weren't a hit, based on the low price for the whole box. I think the Sporting News did something similar with baseball cards (though I think they were all in black and white) I found the black and white pictures to be wonderful, even more fascinating than today's full car, holographic, multi dimensional foil cards. Maybe it was the deep hues.
I called this a treasure find because I liked it. Unlike reality shows, I didn't (and don't) expect to sell the cards for a profit. I managed to get two complete sets from that box--the other, when organized into a quality album, made a decent Father's Day present. I think my Dad appreciated it because he has more than enough ties, and our taste in clothes differs on a scale I wouldn't hesitate to call epic.
Someday, I will probably set the cards up in a couple of frames and hang them on the hobby room wall.
