QSL Card from VE3JBW. I think I received this in the 1970s, at which time this callsign was W.G. (Bill) Bruyn of Ottawa, Canada.
A recent online search revealed an obituary for Bill Bruyn in the Ottawa Citizen newspaper dated 13th January 2009. The call-sign has been reissued to someone else.
He was a Life Member of the Society of Wireless Pioneers - the 'Organization of the "Professional" Brass-Pounders'.
