Does anyone happen to know which items on site are/make direct references to Doctor Who?

I know these custom wearables are, but that's it.

Are there any others? Or maybe any items you think might relate well enough to stick in a collection?

There are a few listed in this thread under "TV Series".

I also know of and Looks like you've got all the CWs I know of.

Thank you both! That's very helpful! :)
