This postcard view of Mission San Carlos was printed by the Curt Teich Company of Chicago using photomechanical processes. It was published in about 1914 by the I. L. Eno Company in San Diego.
The Curt Teich Company manufactured printed postcards between 1898 and 1978 in association with several publishers. The company used the term "photochrom," later "colortone," to describe its color printing processes.
