Everyone stop, this is important
A black and white drawing of three dachshunds arranged vertically, each holding a different optical illusion object in its mouth, and the dogs themselves drawn as if a single line optical illusion. The top dog holds a Penrose triangle, the middle dog holds a Necker cube, and the bottom dog holds a Penrose trident. The dogs’ bodies are elongated in an exaggerated cartoon style. The artwork is signed “@IndieTheIntrovert” in the bottom right corner.
