My mother sells random old bric-a-brac on eBay, and came across a 1960's era reprint of an early 1900's Sears Catalog which was fascinating to me on several levels - the first being that clearly it was nostalgic for folks in the 60's. For me it was a straight up historical document in that it showed literally anything you could order for your house.

Some things would be little changed from today but obviously others would be very different. One of the weirdest things was the patent medication section. Just things like "Dr Fowler's Feminine Medicine" or stuff like that. Lots of promises to help out illness and zero lists of ingredients. It's absolutely bizarre to me, but I suppose not to everyone.
