NY & Detroit 1950. Most carbon copies (of Detroit letters) marked "COPY", about 15 or so letters from Pepsi executives on nice Pepsi letterhead, most with just minor wear else very good. Also includes photos of the Family Case, two promotional pamphlets, an advertising broadside ("…more bounce to the ounce"), etc. The Correspondence centers on the costs of printing, marketing strategies, etc. Sales slumped for the 12-bottle case, so a new idea was being discussed & tested: cans! Interesting collection from a very important year in the history of Pepsi.
