Two technical drawings rendered in sepia tones depict railroad crossing mechanisms from a 1936 patent, with the left figure showing the iconic crossbuck sign and bell apparatus, and the right showing the articulated signal arm in raised position. The composition balances engineering precision with historical weight, rendered in fine linework against an aged paper ground that evokes the original patent document's weathered authenticity. Printed on clear acrylic and made to order in two sizes. A serving piece for the dinner party or a pop of color as a kitchen accent, carrying an independent artist's work instead of a big-box print.
