I picked this up a while ago for a couple of pounds (and have since sold it on to a Sturgeon collector), but thought it'd be good to have him listed here in the forum. It's a print, not an original, but was signed and had the Fine Art embossed mark on the corner. Although he died in 1999, his pictures are still available as limited edition prints from
http://www.sturgeonpublications.co.uk/, where there is also a mini-bio of the artist.
