Looks like some mid-1930's cars in the background of the first photo. You might want to go through the 1934 to 1938 City Directory or phone books for a few of the larger towns in Utah and Washington, looking for Cal's Service or Cal's Veltex. You can sometimes find access to some of those books online. Also, you're in Salt Lake City....don't the Mormans have some kind of huge universal genealogy data base that they offer for research purposes in SLC? A name and/or birth date might be all you need to get more information about Cal. Good luck. John
