Cute sticker asks students to keep their hands clean

This red sticker, which is three inches wide, was affixed to the first page of 1967's "Journey Toward Freedom, The Story of Sojourner Truth."¹

The illustrations of the two kids are so great, I had to post this!

This copy of "Journey Toward Freedom" had been a library book at West Side School in Atlantic City, New Jersey.

Footnotes
1. Sojourner Truth was born Isabella Baumfree. She was called "Mau-Mau Bet" by friends.
