A classic Art Deco era figural Cocktail Shaker in the form of a traditional milk can by Reed & Barton.
The "Milk Can" was introduced in 1938 and came in two sizes - this is the larger size. 11" tall, 64 ounce capacity.

This shaker was a luxury product and was made with Reed & Barton's highest quality plating.
The bottom is stamped Reed & Barton 64oz. There are no monograms.

Shown on page 116 in Stephen Visakay's Vintage Bar Ware where he says it was from 1938 & nickel plated.
Excellent condition except for a shallow dent on the edge of the bottom of the Shaker.
