Photo reference

1 uploaded photo

Overview

A complete set of eight miniature pressed-glass mugs in a vibrant 'rainbow' of translucent colors. These charming pieces feature a classic vertical-ribbed base and were originally marketed as novelty shot glasses or whiskey tasters.

Story

Post-Prohibition America saw a massive surge in home-bar culture, where entertaining became an art form of color and whimsy. These tiny mugs were a staple of the 'Hostess Sets' that became popular as the country moved out of the Depression and into the vibrant 1950s.

Maker / Origin

The Federal Glass Company, established in 1900, was a powerhouse of the American glass industry, known for their 'F' in a shield trademark.

Condition & Value

The glass appears bright and clear in the photos, with no visible 'glass sickness' (cloudiness from dishwasher use). There are no obvious chips on the rims or handles. Maintaining this level of clarity is essential for value, as cloudy glass cannot be easily restored.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

▲ Strong maker attribution with credible period details
▲ Better-than-average condition for the category
▲ Broader demand rises when presentation and finish feel intact

Concerns

▼ Decorative-only demand limits the ceiling
▼ Surface wear or missing provenance can compress the range fast
▼ Regional sale lanes often underperform specialist venues

Best Venue
