This award patch set, based on their size, is probably from the late 1940s to around 1957. I'm not certain if there was a "champion" or "winner" type of patch above the first place patch. Wish I knew for sure.
These patches also came in a few other color variations.
See the photograph of fourteen year old Doug Larson doing "Rock the Baby". His mother wrote on the back of the photograph "[T]his trick is 'Rock the baby' one of the more difficult ones Doug says." Seen on the front of his jacket, on the upper-right side, is the same first place patch that is seen in this exhibit.
