What do you know about Davis Laundry and Dry Cleaners?

I am in Leavenworth KS and was going through some "basement" items.  I came across a wooden hanger and imprinted on

the hanger is:  Davis Laundry & Dry Cleaners, 302 G Street, Davis Calif    Carrere Bros Prop    Phone 228

Would like any information about when this business was in existence since it only has a 3 digit telephone number.
