Mom was proud of the E pin awarded to her when she worked at Boeing during the second World War. It was a production award for excellence and only 4% of the plants doing war work received this award. Each employee of the plant received the lapel pin. During the fairly short time she worked there, she received two of these.
I have a page about her Rosie the Riveter experience, which you can read at Gail Lee Martin in World War II. The photo below shows her in her Boeing uniform.
