These frames could be characterized as "mission", "arts and crafts", "prairie", or "adirondeck". The name "mission" was inspired by Joseph McHugh, a New York furniture maker and retailer, to describe his straight line rustic style furniture. His design was based on a chair that had been made for a church in San Francisco around 1894. The designs were influenced by the Spanish missions of the area, thus the term "mission style". "Arts and Crafts" was the European design name for a similar style. Other "similar" regional styles include "Prairie" from the Midwest and "Adirondeck" from Upstate New York.
