Perhaps I'm the only one who frequents used book sales and buys vintage books?

As someone who grew up loving stories of the "olden days", I enjoyed books that were, well....old. I still do.

Would you consider something like the The Bobbsey Twins or Bunny Brown?
Both by By Laura Lee Hope. You may want to check into her other works as well. I've found them online through ebay and in used book sales, "Friend of the Library" sales, and in antique stores.

It would be out of the norm for sure, but would open some discussion about history.
