Pattern 15309 - Queen Anne / Betsy Ross
This looks like Queen Anne by Tiffin/US Glass. Is it 8 1/4" tall? If so it was introduced in 1925, reissued in 1934 as part of the Betsy Ross line. Again in 1938 it was called Pinafore, with modified molds. The Queen Anne pattern was popular in England and was offered as part of a 7 piece trinket set. [Janice Murphy Feehan]
