This hall tree hook is different than most. It reminds us of the Eastlake era (1870-1890) because of its sharp lines and corners. The brass hook has a long arm with a shorter one underneath. It, therefore, appears to be for a hall tree.
The longer upper arm extends 4 inches, while the shorter one, 1 1/2 inches. The back plate is 3/4 inch by 7/8 inches. The hook is fastened with two wood screws.
Today hall-tree hooks are used in a variety of ways. Who says it has to be used on a hall tree?
