Thomas' Brothers Map of Oakland, Berkeley, Alameda, San Leandro, Piedmont, Emeryville, Albany and Hayward,

This is a very large map w/ some numbers which have been added to it to mark the location of something. They are each located in shopping districts, so it is probably a small, local chain store or restaurant. I can't find a date on it, but i think it's from around 1925. it's very large!
