I've seen that somewhere before, I believe it was in InQuest magazine. If I remember correctly, that was 1999, when the Wizards of the Coast were running an advertising campaign to try to convince long-time gamers that the lost flavor of the classic modules was coming back again. I believe that campaign had ads that said demons would be returning (Burne and Rufus - "What the Hell is a Baatezu?"), among other things. And I think this very cute mocked-up
B2 was featured in another ad in the same campaign. Not real, but amusing.
