Tigerman x Acme postmodern architecture pin unisex

This is in excellent condition, only very minor wear & natural flaws in its manufacturing (see pics 2 & 3, taken through a magnifying glass), none of which is especially noticeable at all. The pin is ~ 6.5 cm tall x 4.25 cm wide & has a pleasant thickness & weight. Primary red blue & yellow with black & white fill in geometric shapes outlined in silver tone to suggest a view down a spiral flight of stairs in bright light & cool shadow. Afternoon sun or a full moon? Questions &/ offers welcome!
