I find this one a far superior parody of Fab than the Chicken Fat from Series 2. A little more detail going on, looks more like a real package, and of course the classic Saunders characters. I have to say this thread is really increasing my appreciation of the 11th Series, which I had pretty much overlooked due to the lack of exposure as a kid - definitely a series I missed completely.
Getting back to Chicken Fat for a minute - not sure if this has ever been discussed before (knowing my memory I’m guessing it has), but I really feel the 2nd Series titles repeated from the 1969 Ads would have been much better if they were redrawn and repainted for the 2nd Series, at least the products in boxes. Because of their relatively tiny size as a small fraction of the Ads art, they lacked the detail typically seen in OS Wackys, along the top and side panels of the boxes. Capn Crud, All-Brain, and Awful Bits come to mind. They’re still great of course, but could have looked even better.
