I just stumbled onto this today and thought what a great overlooked treasure:

 Old Phone Directories

The ones that seem to sell well are from the 1960’s and before and are listed in the Genealogy category. I guess people looking into their family tree find them handy for looking up their relatives.

Now, I bet if you go to yard sales and ask, “do you have any old phone directories from the 60’s or before that you want to get rid of” you may come across some.   That’s not something that most people would think would be worth anything but I’m sure there are people who save every one from year to year.   You won’t run across them veru often but if you happen to find a “pack rat” you may just stumble up a treasure trove in their attic.

Happy treasure hunting!
