This is the 6" fan shaped vase in the hobnail pattern by Fenton. It is called a 6" vase but is actually 5 3/4" tall. It is white milk glass with the double crimped rim at the top. The vase is in excellent condition with no chips or cracks. It is not marked, so it predates 1976 when Fenton began marking all their pieces with the oval logo. Fenton white hobnail began production in 1948. Apparently, they changed the production number or line number of this piece while it was being made, because it is assigned both 389 and 3957 in the Fenton system.
