Graffiti on a Train

Graffiti on a Train. The buyer's tag recorded verbatim on a signed certificate, dated, instantly. Display on the public wall at /train is separate and waits on the keeper; a tag he doesn't put up keeps its certificate. Amounts above the minimum record as tips. Full listing: https://scvd.store/menu/graffiti_on_a_train. MCP tool: buy_graffiti_on_a_train.
