This is a Crinkle glass light pink footed tumbler by Morgantown or Seneca. Seneca calls this pattern Driftwood. Morgantown Crinkle and Seneca Driftwood were made in nearby factories with nearly identical molds and are difficult to distinguish. The only reliable method is to check the rims: Morgantown pieces have irregular rims and Seneca pieces have round rims. This one is irregular. It is in excellent condition with no chips or cracks. The tumbler is 5 3/4" tall. Morgantown produced Crinkle in 1962.
