Found these fun stamps among Grandma's old letters. Couldn't find much about them on the internet other than some ads for "Peppie Pasters" in archived copies of Vassar Miscellany News Volume X Number 26 6 February 1926. The same ad was also run in The Stanford Daily, Cornell, Vassar, Wellesley News, Notre Dame Scholastic and more college papers in 1926 & 1927. I only found 12, wonder if someone gave these to her or she used the other 93?
"Make your friends laugh! Send them letters with the funny Peppie Pasters -- the newest fad. All the rage at Mt. Holyoke, Smith and other colleges. Express your thoughts with these clever little cartoons. Now you don't have to be an artist. There is a Peppie Paster to express every mood and thought you have.
Put them in your diary and memory book. Use them for valentines, dance orders, bridge scores, place cards. Make a Peppie Paster lamp shade. Show your own cleverness in a hundred amusing ways.
Only 10c for 105 stickers, no two alike. They're perforated and gummed like a sheet of postage stamps. Three series, (A, B and C), and more coming. Get them at your dealer's, or put 10c and your name and address in an envelope for one of the series (105 different stamps). Mail at once to White and Wyckoff Mfg. Co., Dept (key), Holyoke, Mass."
I wonder who C.E. Howell was and if he drew the Monopoly man character? Apparently, the artist who drew the mustached Mr. Monopoly is one of the great unsolved mysteries in the history of Parker Brothers. I see the resemblance, do you?
