Basket which belonged to my grandmother

This basket belonged to my grandmother who passed over 20 years ago, I am interested in finding information about it's origin and thus far have not had much luck. The measurements are as follows: 9" across the top, 7 1/4" across the bottom, 5 1/2" tall. My grandparents lived their final years in Phoenix, Arizona and they loved the local cultures. I remember them placing the daily mail in this basket and there are of course happy memories of them when I see it on my table. This beautiful basket seems to be in wonderful shape and I would appreciate any information regarding it's origin. Thank you.
