Jeanette Glass originally offered their version of the Baltimore Pear Pattern in the 1950's. Several years later; (in the late 1960's or early 1970's I believe) they reissued the pattern. In order to differentiate their later pieces, they were generally marked with a single "R" somewhere on the piece during manufacture. The initial is often rather difficult to find and requires careful scrutiny. This creamer & covered sugar each have the "R" which is found just under the leaves beneath the raised pear on the left. The initial is found on one side of the glassware only. No matter which years the glassware was produced, the popular pattern is one of elegance with a raised double pear design on the glass surrounded by a textured pattern of leaves and stems. The creamer and sugar have angled handles. The sugar is often found as an "open sugar" though I believe they all originated with a lid. This set does have the cover for the sugar though there is a chip on the inside rim of the lid which I have yet to be able to capture in a photo. No other chips or issues are found. A pretty set! Covered, the sugar is 6 3/4" tall including the finial knob on top. The Creamer is 5 3/4".
