NEMS-licensed calendars came in surprising variety — from a 10”x12” Louis F. Dow “salesman sample” with blank space for advertisers to print their own business info, to an 11¼”x19¾” glossy 1964 edition starting in March with band bios and “How To Write The Beatles” notes. A redesigned 1966 version rearranged the lineup and added musical-note graphics, while Dow’s promotional kits offered vendors six sizes to choose from.
