I’m assuming the ‘Mexican’ is a butcher throwing his boning knife.Vicky's? Is that an autocorrect of Cocky's?
Carlton were briefly, unofficially the Cockatoos. https://www.blueseum.org/tiki-index.php?page=Other+Club+Nicknames
Not sure what the Mexican reference is. *Essendon were still the Same Old or Dons in the '30s. Weren't Bombers until the '40s. Might be a reference to "Don" being a Spanish title?
Fitzroy were the Gorillas. Looks like North & Hawthorn are missing from the cartoon. Too hard to figure out how to incorporate shin bones, mayblooms or mustard pots in the cartoon?
