Estimated Value

$15-$45

A small cobalt blue glass vessel with a hobnail-style textured body and a fitted lid or stopper-like top. The piece has a flared, tapered form and a rounded shoulder beneath a flat circular top with a central cylindrical finial. The deep blue color and pressed-glass texture are characteristic of decorative mid-century glassware, often produced as a vanity item, shaker, or small covered container for condiments, powder, or trinkets. The surface pattern is evenly molded, suggesting mass production rather than hand-blown artisan work.
