Would you, personally, purchase a photo (at market price) that does not have you, or anyone you know, in the photo, and hang it on your wall? That is, I'm not talking about purchasing a famous photo in hopes of selling later for profit. Nor am I talking about photos of a graduation, wedding, etc., that has people you know in it.
Honestly, no matter how good the photo is, I just don't see myself doing it. But, for those of you that would, what photo (or types of photos) would you buy (again, at market price) to hang on your wall? And follow up for those that would -- if you haven't already bought them, why not?
EDIT: Also excluded are photos of entertainers, to include athletes and political figures.
