After purchasing a box of Saturday Evening Posts from the late 1910s and early 1920s, I decided to scan and post the automobile, truck, and related adverstisements from them. Each ad, unless otherwise specified, is for sale for $3.00 each plus postage. I will combine on postage for multiple ads purchased.
Update: I've expanded to more decades of the Sat. Eve. Post as well as added ads from National Geographic.
