OR Henry Baca - Navajo silversmith. OR Harvey Begay - Navajo. AND, also, I found the HB beer for this mark - looks like their mark on steins but don't know if this has to do with them or not. Overall very good condition - need polishing - both backs move up and down, however, one is more loose but shouldn't be a problem once fastened on sleeve.
Very Art Modern style - probably from the. Has a nude woman and man reaching up high - holding a baby? I have these in a vintage Diplomat box - has a label - sterling - gold finish - so may or not be the original box.
