I've never really been interested in the vintage photos people pay lots of money for -- civil war tintypes or old daguerrotypes of famous people. Nor do I have any interest in the really gross, dark stuff that some people pay top-dollar, like post-mortem photos of babies (yuck) or press photos of old murder scenes or whatever. I collect in these little niches most other people don't care about -- dark-and-weird-but-fun -- and photos that have been written on, which a lot of sellers think hurts their value. All of which is good news for me!
