SIGNED "RIEMAN" PAINTING OF A PARROT & BUTTERFLY

This is a Framed & Signed "Rieman" watercolor painting with a Parrot and a Butterfly.   

I received this from a friend and all she could tell me was it was old and a friend of the family had it made & sent from China while they were there to her Mother.  

On the back of the painting, you can see that it use to have a paper backing. 

I don't know a lot about this painting, but if you need more information, please let me know.  

Thank you!!   

Good
