I CAN DEDUCT $100 FROM THE SHIPPING IF YOU DO NOT WANT THE METAL TINS (I will do my best to keep them organized)

There's AT LEAST 5,000 slides (Probably closer to 6,000-7,000 but 5,000 is a conservative estimate)

about 2% may be personal photos

The rest i'm guessing he would use in lessons. Most seem to be of art or architecture from the last millennium. Seem to be a mix of original slides from photos taken at museums or landmarks or slides purchased from various museums across the world (at least half are copyrighted) 

It's hard to document everything that is included but PLEASE feel free to ask questions. Do to this being such a heavy lot (It will be shipped in multiple packages)  I can not offer returns on the lot
