The Adventures of 19XX, abbreviated as 19XX Adventures, is a retro sci-fi adventure comic IP created by independent creator Paul Roman Martinez. It began as an online comic in 2009 and later released hardcover graphic novels. The core of the story is about a secret alliance in the 1930s that prevented World War II and fought against supernatural evil forces.

The author will also design related toys, based on popular comic characters, featuring a diesel-punk retro adventure style. It is a collectible masterpiece for the niche trend toy market. As an independent comic IP, its related products are not mass-produced. They are all independently created by the author or small teams. Therefore, the market circulation is extremely limited, and the second-hand collection market has a high premium. The rare pure diesel punk-themed collectibles precisely reproduce the retro mechanical aesthetics of the 1930s, and belong to a category with extremely high style recognition in the collectible toy circle.
