AI Item Analysis

This is a retired LEGO Architecture building set modeled after the iconic Arc de Triomphe de l’Étoile in Paris. The model is constructed from high-quality ABS plastic bricks, primarily featuring a color palette of white, tan, and light bluish gray. It stands approximately 4 inches high and 5 inches wide, mounted on a black tiled base plate with a printed nameplate reading 'Arc de Triomphe'. Notable details include detailed stonework texture, miniature white figures representing statues, and a small golden stud at the center of the arch representing the eternal flame. The architecture is captured through clever brick placement to mimic the neoclassical style and corbelled cornices. The piece is approximately 7-8 years old, dating back to its 2017 release. It is in excellent, like-new condition with no visible dust, yellowing of the white bricks, or structural damage, indicating it has been carefully maintained as a display piece. All original elements appear present, including the specialized curved arch pieces and the smooth finishing tiles that denote a premium adult collectable.

AI Appraisal Report

I have completed a visual assessment of this LEGO Architecture Arc de Triomphe (Set 21036). Upon review, the specimen appears to be in exceptional 'Like New' condition. Most notably, the white and tan ABS plastic elements show no signs of UV-induced photodegradation or yellowing, which is a common defect in sets of this 2017 vintage. The printed nameplate is centered and crisp, and the structural integrity of the neoclassical cornices remains intact. The market for retired LEGO Architecture sets remains robust, particularly for iconic Parisian landmarks. While a factory-sealed box would command a premium of $180+, a complete, 'open-box' set in this pristine display condition typically fetches between $100 and $135. Its value is buoyed by its retired status and the high crossover appeal between LEGO enthusiasts and architectural collectors. Value is slightly limited by the lack of original packaging and instructions, which collectors prioritize for archival purposes. Please note that this appraisal is based on photographic evidence. A digital image cannot verify the authentic 'LEGO' stamp on every stud or detect high-quality third-party clones. A full authentication would require an in-person tactile inspection of the clutch power, verification of part-number moldings on the underside of bricks, and a complete inventory check against the original 386-piece manifest. For insurance purposes, I recommend maintaining a dated inventory and high-resolution photos of the base underside.
