Beats me, I don't remember. At that time I had a contract with the Gallery in Canada (they used to purchase outright, but didn't pay much). Since then, they retired. From that period, seventies and eighties, I have only a few records, and only a few photos (analog, of course) - such as this one and a handful more out of at least a couple of hundred works. Most of my stuff from that time is not recorded in any way or form.
