"Learn to Swim. Don't become extinct" A public information poster from Scarfolk Council
This 1972 poster was on my doctor's waiting room wall as well as the Scarfolk infant school noticeboard next to a poster about the dangers of gonorrhoea and nose picking.
The 'Learn to Swim' campaign came about because of a genuine, tragic case: In March of 1971 ten year old Darren Quetzalcoatl drowned in a reservoir after jumping in after his toy Micropachycephalosaurus. However, Micropachycephalosaurus wouldn't fit on the poster.
In honour of Darren, his actual arm was used during the photo shoot for the poster.
