Vintage OBG 1987 iridescent art glass egg paperweight.

Art glass paperweights gained significant popularity in the latter half of the 20th century, with many independent artists and studios producing unique, handcrafted pieces. These items often feature intricate designs, vibrant colors, and innovative glassworking techniques, making them sought after by collectors. The "OBG" designation, along with a date like "1987," points to a specific artist or studio that was active during this period, contributing to the collectible nature of the piece.

This particular egg-shaped paperweight showcases iridescent glasswork, a technique that creates a shimmering, rainbow-like effect on the surface. The swirling patterns within the glass are characteristic of lampworking or flameworking techniques, where molten glass is shaped and manipulated with a torch. Such pieces are valued for their aesthetic appeal and the skill required to create them, often serving as decorative objects as well as functional paperweights.
