The black frog is Cambridge, the green one is probably European!
"The Cambridge Glass Co. Cambridge, Ohio 1930-34" catalog compilation by the National Cambridge Collectors, Inc. has a picture of a handled frog vase #1352 on page 185. It's the same vase only with a handle added.
Documentation for the vase shown was found in The "Crystal Ball", a publication of the National Cambridge club. It says that the earlier style withouth the handle has more texture or wart detail all over the body. It stands 8?" - 9" tall, with no detail on front side except on arms and legs. It has been seen in forest green and ebony and was probably also made in amethyst. The top opening is ground and polished. The earlier style has not been seen with a handle and the later style always has a handle. The later style has been reported in amber.
