My Zelda collection is relatively small. I have Link and Ravio hats from ALBW, a plastic Songbird Ocarina of Time, and a Legend of Zelda wallet. That's basically it, though there are several things I'd be interested in getting my hands on.
I have a Hylian Shield T-Shirt, a Link hat and Ravio hat, a plastic Songbird Ocarina of Time, and a ceramic Ocarina of Time replica (it has broken mouthpiece though). I think that's it, can't think of anything else atm.
I have a Hylian Shield T-Shirt that my friend painted for me. I also have ALBW Link and Ravio hats. I recently ordered one of the Songbird Ocarina of Time replicas, which should be here within a week!
