This tan plate with blue rim and extraordinary artwork is from Tlaquepaque in Jalisco State Mexico.
The detail in the colorful depiction of a sombrero-wearing Mexican amid cacti and agave and beneath a distant flock of birds is among the best we have seen from this town near Guadalajara, known for this type of pottery.
It is typical of the work done in the 1930s up into the early 1950s, but all factors convince us it is early 1940s.
It is 8.25" in diameter, and has "MEXICO" in raised letters on the bottom, typical of the era. It is very good condition. It weighs one pound without packaging.
