Yes, it's Fenton. This vase was sold on QVC in the year 2000, and it's pictured on p. 96 of the book "Fenton Glass: Especially for QVC." The color is iridized Spruce Green Overlay (Spruce Green on the outside, Milk Glass inside). This is a blown piece, so the logo (Fenton in script with a small 0 underneath, all within an oval) can be very hard to discern. That's one of the things we have to live with when making handmade glass. The pattern, Jacqueline, originated in the early 1960s and was named for First Lady Jacqueline Kennedy.
