Overview

A large, vitreous china oval platter from the 'Informal' line, featuring a stylized wildflower motif in muted blue, green, and yellow.

Story

In 1958, the American dinner party was undergoing a radical transformation as the rigid formality of the pre-war era gave way to the relaxed, suburban 'hostess' culture.

Maker / Origin

Ben Seibel was a titan of 20th-century industrial design who studied architecture under Eliel Saarinen and brought a sculptor's eye to everyday objects.

Condition & Value

The platter appears to be in excellent vintage condition with no visible chips or heavy utensil marks. The backstamp is crisp and fully legible, which is a plus for collectors. Excellent condition for this line typically commands the higher end of the price range.

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
