Lot, Japanese Geisha Ware, Very nice Different Era's

Geisha tea set purchased for $12 at church thrift shop with a $3 donation. I believe they are from different Era's cause of the back stamps are different on a few. One has a stamp of Japanese writing, one has "Japan", and another has a cherry blossom with letter "T" inside cherry blossom. But all are hand painted an looks beautiful it's truly a piece of art. Most of the collection has the cherry blossom stamp so I believe it could be from around the 1930's maybe I'm not sure any info will help thanks.
