So it's Thistle in the dark tops with the light sleeves? Don't remember seeing this strip before. Is it blue and white and were both teams wearing change strips because of the red and yellow / black and gold clash?
Apologies for all the questions but I'm only young (57!).
Looks like Hampden, maybe early 50's, but it doesn't look like Thistle and doesn't look like full blown international match either. I'm guessing there's a Jag in the photo playing in some other representative match. Am I close?
