Very rare 1930's private purchase USMC EGA cap insignia (Eagle, Globe and Anchor). Terrific detail throughout with longitudinal and latitudinal lines. The eagle's right wing reverse has the MEYER METAL logo and the reverse of the left wing has the NS Meyer shield logo. The lower right corner of the eagle is darker then the rest of the EGA. Presumably this had something to do with how it was stored but whatever the reason my golden rule is to just leave it alone. This is much more subtle then it looks in my attached photo which uses a heavy flash. This pattern is sometimes called the China Marine but I do think there is any particular reason for this. Great piece of insignia.
