Easter Egg roundup: all the cameos and references

So the finale had lots of references and clues to various stories, some we may see again and some we may not. Some were obvious, some were briefly glimpsed, and others may be more hidden.

I though it would be good to try and make a list of everything that people have spotted. 🙂

I know we have a thread with screencaps and details of the library books, and one discussing who all may have been spotted in the Land of Untold Stories.

But, what else is there? Were there other clues hidden in the rest of the episode?

For example, I think someone mentioned a painting in Rumple’s hotel room, but I didn’t see it. Does someone have a screencap of that? And whatever else people have noticed that might mean something, can you post it in this thread?

And maybe we could have a master list of character & story references spotted, in three categories: in the library books, in the Land of Untold Stories, and anywhere else in the two part finale. 😀
