This antique advertising glass paperweight features a rectangular form with rounded corners, constructed from a thick block of clear glass. The top surface is finished with a ruby-red flash or stain coating. The face is etched in decorative cursive script reading Regnier & Shoup Crockery Co. St. Joseph, Mo. This etching is filled with a light-colored pigment that appears to be the remnants of original gilding. The Regnier & Shoup Crockery Co. was a prominent wholesale dealer of china, glass, and queensware based in St. Joseph, Missouri, during the late Victorian and Edwardian eras. The ruby flash technique was a common decorative style for souvenir and promotional glass items between the late 19th and early 20th centuries.
