Mac, I didn't know you were Batman or are you Alfred cleaning it out? Could you see Batman relaxing in the cave (Kansas City) mounting stamps in his album? Of course, he would have a very expensive collection being a millionaire.
I probably lean more towards Alfred and getting into spring cleaning. Currently toying with the idea of stampoffers to thin out some more of the herd. Don't forget Batman originally started off as a detective, perfect for investigating stamps.
