Gib screenshots so I can figure out what you're missing. I assume you don't mind spoilers.

Those are event relics/cards. You'll get them eventually by doing ?-rooms.
Well, maybe not the poop. You might never ever see that one. : p

Important to note: they are not locked per se, you just have not discovered them yet.

The card is from an act 2 event. Hovering over the deal even shows you what you get.
The first 2 relics sure look like more faces, don't they?
The third one completes your collection of books.
The fourth is what you get for giving something equally crappy to spirits.
The fifth you'll get eventually in whatever act, just like the masks. (Again, mouse over stuff.)

#Edit:
I'm probably dum and the relic doesn't get shown. But like it says "special relic", so.

Ah, so they are not locked, they are just not yet seen. Thx guys!

I will try mouse over next time I get an event that I ignored until now. For example the event that gives you 5 Apparition. (never accepted that one - yet)

Guess what that one missing card is ;)
