Any places to sell (non dirty) photographs?

I'm talking landscape, sunsets, sunrises, beautiful shots of buildings, construction photography and even factory photography.

I have a collection of my own and my father's photography work, thirty years worth of wonderful unused photos that I'm thinking of unloading.

Also, any auction sites for rare pictures? I have pre-digital era 72x52 sized photographs, not posters, photos, of the Saudi holy cities to unload as well.
