Vintage Patterned Paper: Black and White (Set of 3)

This set of three black and white theme patterned papers include one featuring what might be bamboo, another possibly rattan stitching, and a third an indecipherable pattern. We believe they were stamped or pressed into the paper. The paint atop all has a chalky texture, but does not come off when touched.
 
All are in okay condition considering their age. Burr is written on the back of one sheet suggesting they are from the 1920s-1950s, when the Burr sisters were most active as artists and collectors. They appear to have been stamped or printed within a heavy press. See photos of the backside where you can see the patterns pressing through. The intention may have been to use these as book covers.
 
They have minor some foxing / spotting on the back and a couple of minor tears along the edge as shown in photos.
 
Each sheet H 16” x L 22”
