"Any treat will stop a trick . . . as long as it's from POST TREAT-PAK"

October 27, 1958.  LIFE Magazine.  I really like the DICK SARGENT illustrations for POST Cereals.  "No tricks this Halloween when the treat's from POST Treat-Pak.  Six boxes of snack cereals especially for children.  Sugar Crisp, Sugar Rice Krinkles and new POST Alpha-Bits . . . every one -- fun!"
