This is a great example of a 1920-1930's ruby glass cocktail shaker with a silver overlay by Rockwell Silver Co. of Meridan, Connecticut. Their letterhead would read "The Rockwell Silver Company - Silver Deposit Manufacturers, Decorators of Glassware and China." The "Rockwell" trademark earned the respect of the trade as they were pledged to the policy of producing an artistic and harmonious product. The firm had been a leader in the production of depositware since its beginning in 1907. This is a action packed big gamefishing scene with two guys in an open 1920 "skiff" type fishing boat going at it with a giant swordfish. The super rich details even include the boats name "Spree". The American author Zane Grey was the first to write about big game fishing for tuna and marlin from a small motorboat with a fishing pole, and made the "Sport" popular. Our man Hemingway later turnd it in to legend. This is a superb set and includes 2- 3 oz Cocktail glasses (the only ones i have ever seen) with the same detailed motif. I don't think they wher meant to be actually used for making drinks but more as trophies or gifts- also they are totally functional. 11 inch tall, 4 inch the glasses.
