Frolicking Bears- U.S. Glass
An extremely rare pattern, Frolicking Bears is known only in the pitcher and tumbler, always a sort of olive green. Both show bears in various playful poses against a mountain backdrop with grape vines, leaves, and bunches of grapes around the top. For a long time it was unknown who the maker was, but in 1982, William Heacock confirmed that it is a U.S. Glass pattern. He located the pattern in a 1910 U.S. Glass catalog that is on file at the Corning Glass Museum.

In 2014, Tom Mordini reported a ruffled hat made from a green tumbler.

The design has been used by the International Carnival Glass Association for souvenirs.
