I know the santa in your photograph. His name is George.
I am not sure of his surname as everyone calls him Santa.
He stayed in Collie Cottages on the main street in Aviemore until recently.
He is now in respite in Kingussie at the Wade Centre. I hope this helps.

Your site is great and I have been looking for old pictures on the
internet of Aviemore with not much success.

"UPDATE"
Here's "Santa" George at the Glenn Centre (from the Strathspey and Badenoch Herald)
