Fenton produced it's original Dolphin Handled pieces in the 1920s and 30s and I believe this bowl dates to that era. It is unmarked and the more recent Dolphin handled pieces that Fenton made appear to all be in fancy finishes such as Stretch Glass.
This piece is a plain, grassy green with a paneled design and two upturned sides. It would make a beautiful card holder or candy dish.
The dish measures 6 3/8" long and 5 3/4" wide. It is 2 3/4" tall. In excellent condition this piece has no chips, nicks or cracks at all and no signs of scratching or wear from use.
