These glass bear bookends were produced by the Blenko Glass Company around 1975, designed by Don Sheppard (often marked as DAS).

Blenko Glass Company, founded in 1893, is renowned for its handcrafted art glass and has been a significant contributor to American glass design throughout the 20th century.

These textured glass bears exemplify mid-century modern decorative art and are sought after by collectors of American art glass and mid-century design enthusiasts. The distinctive textured surface and clear glass with subtle color accents are characteristic of Blenko's artistic approach during this period, making them valuable to collectors who appreciate both their functional purpose as bookends and their artistic merit.
