Description
Vintage Mid-Century Libbey Rock Sharpe cocktail glass featuring an elegant internal optic rib design. The glass transitions from a smooth, wide bowl into a unique concentric ringed base, providing a subtle 'industrial deco' aesthetic. Perfect for martinis or classic cocktails.
Key Features
Optic ribbing creates beautiful light refraction; recognizable Mid-Century Libbey silhouette; high-quality vintage glass weight; popular among 'Mad Men' style barware collectors.
Authenticity Indicators
Libbey glass from this era typically had no maker's mark or a very faint 'L' in a circle at the bottom, though many were unmarked. The specific concentric tiered base is a known Libbey/Sharpe design cue. Confidence: High.
Flaws to Note
Possible minor 'shelf wear' on the bottom of the base (scuffing). Check for 'glass sickness' (permanent cloudiness) caused by automatic dishwashers, which significantly devalues vintage glass.
Selling Guide
Where to Sell
Etsy (best for vintage barware enthusiasts), eBay (best for collectors looking for specific replacements), or Facebook Marketplace if selling as a larger set.
Selling Tips
Photograph against a dark, solid background to make the optic ribs pop. Use keywords like 'MCM', 'Optic Ribbed', 'Atomic', and 'Depression Era Style'. Always hand-wash before photographing to remove smudges and highlight clarity. Double-box when shipping.
