I ended up with a small creamer marked “USA Bauer 1102.” I did some initial research and discovered it is part of the Moonsong collection in Desert Beige (see photo of ad, I added arrows).

I can only find a handful of listings on ebay and entries in the price guide here, but none of them are the same piece that I have. I know rare doesn’t always equal valuable, so I was wondering if anyone knew enough about this line or Bauer in general to say whether I should keep searching for clues or spend my time elsewhere.

Thanks in advance!
