Help with a signature on a aquatint etching

Hello All
Picked up this etching a couple of days ago. It looks like the signature should be easy to look up, But nothing! The etching is in very good condition. I found the etchings subject matter interesting and was wondering if it might be for a book illustration? Any info would be greatly appreciated.
Thank You
Kevin

FP Imayavo? Imayaro?

 

He's playing a mbira which would lead one to think scene set in Zimbabwe or roundabouts.
