This humorous, retro-style crewneck features a bold black line-art Tyrannosaurus rex surrounded by a circular flowchart joke, blending vintage science illustration with playful wordplay. Inspired by the apex predator of the Late Cretaceous Period, the distressed black graphic pops against a clean white background for a classic natural history look. Made from 50% ring-spun cotton (high-quality cotton) with a soft, sensory-friendly feel. Every shirt purchased plants a tree, and the material is eco-friendly.
