Looking for Bulgarian Artist from the 1980ies

Hello,

I own this wonderfull sculpture, which I bought as a student in Nessebar in Bulgaria in 1990 in a small Art Gallery.

Unfortunately I was to young and unexperienced, so I forgot to keep the Name of the Artist. I remember the name of the sculpture was something like „the Virtuose“

Does anyone has an idea, who could be the Artist or where I could get Information about him.

The second Photo shows a kind of signature at the foot of the sculpture.

Thanks in advance
Thomas
