Thanks to Chemgal for sending this in, and identifying two areas of doubt: 1) Though not a public designated observance, the 7-Eleven company, at least in Canada, has traditionally marked the 7/11 date with promotional giveaways. Is Mallett just unaware of this? 2) Wot th’heck do the last two panels mean? A mystery, in themselves and in their relationship to the first nine panellettes.
P.S. A Geezer identification question — Do you remember when 7 AM to 11 PM were in actual fact the hours for 7-Eleven stores?
