Trying to identify a Sunbeam poster that I have

[65sunbeam]

I got this large poster many years ago at a Sunbeam event and would like to get some copies made-there is a designer's name but it is not readable-anyone know who made this? I don't want to step on any toes if I make copies.

Seems to me one of the Sunbeam suppliers in the US used to sell this poster?

I found an old eBay listing in the UK where one was sold for 125 GBP. It also said the artist's name is Hutchinson and these were done about 40 years ago. And also that 150 prints were made. I think these were sold at the first SUNI in 1989.

Nice poster! I hope you can identify the artist.
