I think a partial on the marks reads "Hand Painted", written oddly so that the P looks like a B.
If so, I more associate that with Nippon. Possibly a maple leaf Nippon mark next to it?
The mark (to me) although somewhat hard to see, appears to be a Nippon Maple leaf-
“Maple Leaf Nippon”, dates back to 1891. Found in green, blue (shown) & magenta. Van Patten’s #52. This mark should be 1/4″ high. Known fake Maple Leaf backstamps are 1/2″ high.
