Anime Boston

I was reading the swap meet rules and I saw it wasn't really clear on whether or not only official merch is allowed. Like I got the no bootleg parts, but I'm unsure if fanmade items are fine. I have a lot of old stuff from zines that I'm not really into anymore, like prints, keychains, pins, etc etc that I was hoping to trade but I wasn't sure if that's allowed or not.
It's pretty obvious they're not official items as they have the artist's distinct styles and original designs that don't resemble official merch, so I'm assuming they're okay? But I wanted to double check first before I bring them.
Thanks
