I found this adorable short film, 'Wise Cottage at Dymchurch', made in England during the 1940s; it follows a family's fun day out at the beach. As per the British Film Institute description, "Back at home, in Wise Cottage, members of the family are seen relaxing and smooching - with a man tickling a woman". The tickling scene is at 2 minutes 25 seconds: https://player.bfi.org.uk/free/film/watch-wise-cottage-at-dymchurch-1940-online
