Mongo is appalled. The Mongo is Appalled T Shirt is a bold, gloriously absurd declaration for the sci-fi book lover who appreciates the vintage princess cat riding a dinosaur aesthetic and the specific comedy of a cat named Mongo who is deeply, fundamentally appalled by whatever is happening around him. Whether you are a sci-fi enthusiast who loves cats and dinosaurs and finds the combination of all three in vintage style deeply satisfying, a book lover who carries the Mongo is appalled energy as a personal identity, or simply someone who believes that a vintage princess cat riding a dinosaur is the most perfectly specific shirt concept ever conceived, this sci-fi book lover tee is made for you.
This shirt runs true to size with a relaxed unisex fit. Please refer to the size chart before ordering and allow up to 1 inch variance due to the handmade production process. For a looser, more oversized look, consider sizing up one size.
This tee carries the Mongo is appalled energy and the vintage princess cat dinosaur sci-fi aesthetic in a design that makes the book lover's identity impossible to miss. The bold graphic is printed with high-resolution digital ink that stays sharp and vibrant wash after wash. The preshrunk cotton means no shrinkage surprises, and the classic unisex cut makes it the most perfectly specific shirt at any sci-fi or book lover gathering.
