Elijah McCoy Postcard Set (Pack of 10) — Continuum: The Patternmakers | Roots and Ties

His invention worked so well — and was so poorly imitated by competitors — that customers started asking specifically for "the real McCoy." The phrase stuck.

Each pack includes 10 postcards, all featuring the same design — perfect for mailing, gifting in bulk, or keeping a full set for yourself.

Front: Grid (structure, planning, disciplined intelligence) and Path (direction, forward movement, progress shaped through persistence).

Back: A personal letter written in his voice, plus a short note on his place in the legacy.

Read more on his Field Notes, and decode every symbol in the Visual Key.

Mail it, gift it, or keep it — every Roots and Ties postcard is made to be shared.
