all time Favorite module cover.

I vote for G 1-2-3 with Ravenloft a close second.

Ravenloft module factoid: There's nowhere in the module, i.e. in Castle Ravenloft, that corresponds to the depiction in the cover art.

Yes there is. Strahd in this pic is stood on the balcony slightly below the castle that peers out over the Valley where the village of Barovia is located.

After some thought I have to go with Temple with Ravenloft a really close second.
