Oooooh. Shiny. Look at all the old snapshot albums that people sell on eBay. Take your pick: 1930s sailor's (the seller who added "GAY INT" is probably reserved a special kind of placement in hell), Civil War, Victorian, WWII, 1920s Texas. The list goes on.

Scans from these would make an awesome photo blog. One could harness the photos in those albums to put together an amazing collection. Probably 10 grand invested today would turn into one hundred 5-10 years from now. Too bad I don't have disposable income.
