Depicts a Boeing EC-135 aircraft. Likely a desk or wall identification plate for display in command posts or briefing rooms. 7″ × 4.5″, thin brushed aluminum with black etching. SAC Headquarters Building & Missile Display. Shows the main HQ building with missile monument and flagpoles. Same etching method and size as above. Likely part of a presentation set or commemorative desk display produced for senior officers or visiting dignitaries. The Looking Glass EC-135 aircraft was an airborne command post that mirrored SAC headquarters, maintaining 24-hour readiness to direct nuclear forces in the event of ground communication failure. Plaques and etched aluminum art pieces like these were commonly produced by base machine shops or Lockheed, Boeing, or Air Force engravers as commemorative or internal presentation pieces-not mass-produced souvenirs. Authenticity Indicators: Hand-finished casting marks, non-commercial construction, period-correct aluminum thickness, and accurate heraldic design. Surviving examples typically originate from retired SAC personnel estates or base decommissioning lots. Collector Interest: Strong among Cold War, U. Air Force, and aviation memorabilia enthusiasts.
