Japanese Wood Block Painting

Japanese Wood Block Painting

Approximately 12" x 14"

Picked this up recently at a sale. Don't know very much about it and have not found any matches. If anyone can read the signature stamp that would be helpful.

The back has some type of sparkly paper board. Some dimensions are written on the back and possibly frame info? It did not have a frame when I bought it.

Has some dark spots but overall it's in very good shape.
