...which years he wore his JOFA helmet with the Leafs?
I'm trying to identify the date of a photo of him that I have in my possession.
Thanks in advance.
I think this photo's from his rookie year.
He only wore that version of the Leafs home shirt in his first two seasons. They got rid of the string on the neck in his 3rd year. I think most of the pics I looked at from 1974-75 he seemed to have black string and wore a short turtle neck, but don't quote me on that. Your pic he's wearing light blue string, and a t-shirt under his jersey.

The interesting thing about your pic is his Yellow Koho. I can't find any other photos of him with that version of a Koho, except for his 1974-75 Action Stamp. In all likelihood, the photo for that stamp would have been taken from the previous season.

Also, judging by this footage, it looks like the Leafs changed the colours of the dashers on the boards from Light Blue to Yellow in 74-75.
I believe this was Maple Leaf Gardens in 1973-74, and that this photo was taken during Bruins vs Leafs playoffs.

Plus this to back up my dasherboard theory:
Of course the stick, strings, and t-shirt could have changed at any given point, one way or another, or back again... so I'm basically just speculating. But all this leaves us with 1973-74. Leafs played 80 games, 40 at Home, including the playoffs. Borje played in all of them. There's 40 possible dates that photo was taken. That's as close as I can get in an hour's work, without more clues.
