Mod 1970s Retro Style Geometric Design Glass Coaster

A dynamic abstract composition featuring two bold circles—one blue, one green—linked by three flowing bands in orange, magenta, and yellow. Each stripe is bordered by crisp lines, curving gracefully across a black background. The interplay of shape and colour evokes 1970s graphic design, balancing visual rhythm with sculptural simplicity. The result is a harmonious, retro-inspired piece that captures motion, contrast, and editorial clarity.
