I purchased in Middletown, CA, the subject undated RPPC (Real Photo Postcard) (not postally used) depicting a young couple and identified on the back:
"Mr and Mrs Biavaschi"
This photo was found in a box containing other Sonoma County photos.I believe the man in the photo is Emil Alexander Biavaschi, born 21 Aug 1884 in Italy (immigrated 1906), died 14 Jun 1958 in Sonoma Co., CA. He is listed in 1910 Census data for Precinct 44, Deer Lodge National Forest Preserve, Silver Bow Co., MT; the 1920 Census data for Santa Rosa (resided at 615 Olive Street), Sonoma Co., CA; and the 1930 and 1940 Census data for Santa Rosa (resided at 423 So. A Street), Sonoma Co., CA. His WWI draft registration card is available. Emil married Ethel Lemmon, born about 1889 in MI.The couple had two children: George Emil Biavaschi, born 21 Apr 1915 in CA, died 1 Jun 1991 in Sonoma Co., CA; and Mary E. Biavaschi, born 29 Apr 1916 in CA. Emil was employed as a stock ranch farmer in 1910, as a truck driver in 1920, and as a police officer in 1930 and 1940. A short biography appears on the City of Santa Rosa web site. Emil was appointed Chief of Police of Santa Rosa in August 1935, but stepped down to patrolman in February 1939, serving in that capacity until he retired in November 1953.
