This is Saalfield's #1513 Outdoor Paper Dolls, published in 1948. I have the original number book, but there was a different version with more clothes and the front cover dolls dressed differently. I have scans of some of the missing clothes and the original dolls.
This is a great *teen* set. I am fascinated by the shorts/ascot/bathrobe outfit on page 2, as well as the peek-a-boo front on the girl's lounge set.
