Walter Merga

[Troika]

Does anyone know where I can get information on Walter Merga?. As far as I know he is a Marple artist.I bought 2 lithographs of his when I was in Marple in the 1980,s and brought them back to Australia and I would like to keep information about him with the art. When I worked at the Nat West Bank in Marple I do remember him but do not know if he is still alive. Any information would be appreciated.
