Typically this design is seen as a three dimensional solid plastic figure 3.5" tall. Here the figure is molded high relief plastic, but open on the reverse with a pair of clear tubes joining a round black plastic water holding compartment at the base. The tubes protrude 1/16" and 1/8" at the front of her breasts to deliver water stream when the compartment is squeezed. Figure can be made to rest on a shirt pocket edge thus hiding the compartment to catch the curious onlooker by surprise. Compartment does still have some flexibility and may still function, but we did not want to compress it very far for fear of cracking. Circa mid to late 1940s and inspired by the famous WWII slogan. Only example we've seen. Displays Mint.
