Historical Context & Dating

This specific backstamp holds an interesting piece of history: it lists Texas as the "Largest State in the Union." Because Alaska did not become the 49th state until 1959, this wording explicitly places the production of your plate between the early 1940s and 1958. 

The back also features historical text noting key dates (such as its 1845 admission to the Union) and the "Six Flags" that have governed the territory.

The estimated market value for this Vernon Kilns Texas "Lone Star State" blue transferware plate typically ranges between $22.00 and $48.00.
