This is an Exquisite antique, Victorian art glass, Rubina punch / lemonade cup, with an applied strap handle, and a ground, polished rim and pontil. This popular Victorian 'Thumbprint' art glass design was made by a few well-known glass makers during the 1880's, including Hobbs Brockunier & Co., Phoenix Consolidated Glass Co., George Duncan, and Northwood Glass Co. Originally called "Polka Dot", or "Spot Optic" - this art glass pattern is now commonly referred to as: 'Inverted Thumbprint', or " Baby Thumbprint". Made from a mold-blown 2-step process in which the raised dots are on the inside of the glass and the exterior is smooth. This gorgeous color is called 'Rubina' which is a deep Cranberry or Ruby red color glass 'fading' to crystal, clear glass. Measures 2 1/2 inches high X 2 1/2 inches across the top rim. In Excellent condition - No chips or cracks - just a tiny 'crease' on the surface near the top, and a bit of roughness where the handle was applied - both from the manufacture process. Glows a strong yellow-green under uv blacklight to further verify age! Outstanding!
