I took some time editing some photos I found on the internet. I made them look somewhat like what we should expect to see this upcoming season.
Toronto Maple Leafs
The NHL logo at the neck will probably have a white background such as their current white jersey does now.
Again, not much to say. It's a retro jersey.
Same as their Winter Classic jersey, just obviously without the patch.
I didn't edit this photo, I just found it on some site that I cannot remember now.
Simple and clean. Maybe too much black for a Flyers uniform.
