davidcyclebackThe mount is consistant in style to when Collins was a player.
Many mounts had thin front and back layers, and if you tear off a corner the middle is often a different color. If the front has an embossed texture, there's no reason to beleive it isn't an vintage mount.
I can't comment on the photographic print itself from an online image.
Chickering did a variety of Boston sports photos. He probably photographed the Harvard football team. The cabinets of his I've seen have had his name on the mount.
The photographic prints on genuine cabinet cards sometimes have crooked cuts. They usually are straight, but sometimes have a bit of a handcut-- especially oval prints.
