The "Favorite Bavaria" stamp was a specialized export backstamp used by the prominent C. Hutschenreuther porcelain factory in Bavaria, Germany.  Pins not included.

• Target Market: It was created exclusively for the American market between roughly 1900 and the 1930s. The explicit use of the American spelling "Favorite" (instead of the British "Favourite") highlights this connection. 

• The "Whiteware" Craze: Hutschenreuther exported these pieces as undecorated, white porcelain "blanks". They were shipped to North America to satisfy the massive early 20th-century trend of amateur and professional china painting. 

• The Decoration: Your shaker’s lovely blue forget-me-nots were likely painted by an artist in an independent professional studio—such as the famous Stouffer Studio in Chicago—or by a talented hobbyist artist during a Victorian-era home decorating guild movement.

• The estimated fair market value for your antique "Favorite Bavaria" hand-painted porcelain shaker ranges between $25 and $60 USD in today's collectors' market
