It has been mentioned what happens when you forget to include the proper quantity of frames in supers added to hives.
Earlier this season I was adding supers and overlooked including the proper amount of frames in one. Later when I went to harvest honey I got this surprise:

that looks huge lol. was it hard to get all the bees off it?
I just smoked them out of the nooks and crannies.
Usually if you only leave out one you get one nice comb that isn't attached to a frame. :) I usually scrap the nice ones if they are honey or tie them in a frame if they are brood.
Usuually if you leave out two, you get the kind of mess you have.
MB, I believe you are correct. This is probably two missing frames on the one side of the super.
