Nice wrestling poster from the 60s

[SeasideMark]

This poster came in the shop today for an 'all star' wrestling bout in Bridlington in the late 60s or early 1970s.
Not being a big fan of the grapple game as a kid back then, I was fascinated by the names - Honey Boy Zimba 'A very colourful wrestler' made me smile, wouldn't happen now!
The one that intrigued me was Don Vines as I recalled him playing pro Rugby League so I wiki'd him and found he had quite a good career with Oldham, Wakefield and St Helens in a variety of positions. He began his career in union with Newbridge down in south Wales.
I can't find much of the other rugby player on the bill - Barry Douglas - so would be interested if anyone has any info.
There's a link to a clip of him fighting Zimba on World of Sport below.
The poster has been rolled up tight for years and is in immaculate condition considering the cheap paper it was printed on.
I found it a fascinating item from a period within my lifetime, but which, compared with today, seemed like a totally different world. If it's of interest to anyone on here I'm open to reasonable offers.
