Happy 4/20 from George Contreras, one of LA’s most notorious party poopers! Conteras was born in LA in 1888 to a Mexican dad and a white mom. He began working for the DA’s office in 1919 and in 1922 was put in charge of the city’s “Booze Squad,” which enforced prohibition.

This #loyalfam looks happy, right? (courtesy @lapubliclibrary). Lots would've angered Mexican angelenos in 1915 when this pic was taken. But, if the Arroyos had enough $ for this pic, they were probably doing ok. #oldlosangeles #vintagephoto #throwbackpicture
