I was idly watching a lovely b/w film from 1963 on BBC iPlayer called 'Let's Imagine - A Branch Line Railway with John Betjeman' - you can watch it here - https://www.bbc.co.uk/iplayer/episode/b03495yn/lets-imagine-a-branch-line-railway-with-john-betjeman when suddenly in front of me an 'advert' for 'Airfix' appeared 9'54" into the film - here's a 'still' of it. Historic Airfix advertising! So maybe we can collectively find more examples of 'Airfix' advertising of yesteryear?
