The stopper on the left is a beautiful example of an older "Drinker."
When you press the wooden lever in back his mouth opens, as his arm brings
the glass in his hand up to his mouth. When the lever is released
he goes back into the original position. The one on the right is
an example of what to avoid. This tacky one has the dreaded plastic
head. Variations on the Drinker include his drinking vessel....mugs,
bottles, cups, steins, and the usual differences in attire.
This is a very unusual "Drinking Bear" stopper that works on the "twist-peg"
method. Twisting the small wooden dowel causes him to lift the bottle
up to his mouth using both paws. The twist-peg is found on some of
my favorite stoppers.
