Vintage rectangular door knob back plate / escutcheon with an Eastlake-influenced design, dating to the late 19th to early 20th century.

The restrained linear pattern and rectilinear form reflect the Eastlake movement’s emphasis on geometry, craftsmanship, and honest ornamentation — a departure from the heavier Victorian excess that preceded it. Pieces like this were commonly produced during the transition from the Victorian era into the early 1900s, when functional architecture and decorative restraint began to converge.

This example shows copper tone visible through its original finish, consistent with aged copper-plated architectural hardware of the period. The wear is even and authentic, preserving the visual language of a piece that has lived within an interior rather than being refinished or modernized. Unmarked.

Well-suited for period homes, thoughtful restoration projects, or architectural replacements where proportion, age, and material history matter more than uniformity.
