I have 4 official Habs jerseys - all home red - one is #11 Koivu, I have one of with the "CA" logo they used during the centennial season and a couple other standard red ones. I've had a bunch of player t-shirts over the years too. The only one I have right now is a red Drouin shirt.
I also have a few items they gave away at games: 3 mini-pennants from jersey retirement games, 5 bobble heads (Koivu, Theodore, Beliveau, Benn and Kovalev), and two soccer-style team scarves. And a bunch of playoff towels. I got lots of other nick knacks at games too but they were not worth keeping (think big fingers, flags, car flags, bags, etc...).
