Nine colored circles arranged in a grid pattern represent the Tokyo Metro lines, each labeled with a single letter (G, M, Mb, H, T, O, Y, Z, N, F) in clean, modern typography against a soft peachy-beige background. The composition is orderly and graphically striking, presenting the transit system as an accessible visual reference with its Japanese title "東京メトロ" and English subtitle at the top. Printed to order in our Denver facility on a cushioned, lightweight mat that rolls up and travels with you. Real art under your feet through every practice, not a generic store-shelf print.
