D&D 5E "Easter Egg" on the cover of Yawning Portal

[Morrus]

WotC says there are 8 easter eggs from all of the classic adventures in the cover of Tales from the Yawning Portal.

I reckon I see a Frost Giant Jarl, for one; since I don't have the book yet, I'm not familiar enough with any of these to say.

What's he holding anyways? I feel stupid.

Well, I'd imagine that skull in the upper left is supposed to be Accerak (sp?) from Tomb of Horrors.

 

[Remathilis]

Nix/Nox from White Plume Mountain is the face just above the book pile.

I wouldn't really call them easter eggs if they're plainly visible in the image.

Easter Eggs for Dummies?

I don't really know enough about the old adventures being updated to be able to pick out anyone. Actually, I don't really know what adventures are in the book, still pre-ordered it though.

This. If they're actually easter eggs, then I'm going to assume you need a better image to pick out the details. Some guesses are: 1) whatever he's holding in his hand, 2) the mug is a reference to some bottomless mug o' something, 3) the coin is something interesting, 4) at least one of the books has an interesting title or visible text.

None of the faces can even remotely qualify as "easter eggs". A more appropriate phrase would be "relevant artwork" or even just "topical".
