Overview

A classic lithographed steel vacuum bottle featuring Colonel Steve Zodiac and Venus from Gerry Anderson's 'Fireball XL5'. This piece is a quintessential artifact of the 1960s 'Supermarionation' craze and the global obsession with the Space Race.

Story

Named after Castrol XL motor oil, this 1962 series was the first British show sold to a US network. It followed the World Space Patrol in the year 2062, fueling the dreams of a generation watching the real Moon landing approach.

Maker / Origin

King-Seeley Thermos Co. was the titan of the school lunchroom, dominating the market after merging with the American Thermos Bottle Company in 1960. They turned everyday utility into a canvas for pop culture, immortalizing everything from Barbie to the Beatles on tin and glass.

Condition & Value

The exterior lithography shows some light scuffing and minor paint loss consistent with age. The red plastic cap appears intact, but the internal glass liner and stopper must be checked for cracks or missing parts. Minor surface wear reduces value by roughly 20%.

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
