Caps for Sale! Fifty cents a cap! Everyone knows the classic favorite by Esphyr Slobdkina and today we spent the morning making our own paper hats to wear on this hot summer day. Did you know that Caps for Sale was first published in 1940? Many parents remembered reading this book as children themselves, and everyone gathered around to hear it read aloud. This was part of the Portland Downtown series, and took place most Wednesdays in July. Check out the fun!
