Lily of the Valley, Fenton
Fenton has produced a number of shapes in this pattern including the rosebowl, covered candy, and bud vase shown above. While Fenton made a pattern of the same name during the classic era in pitchers and tumblers, they are quite a different pattern and so far as I know, have not been reproduced.
