The typeface is characteristic of Butlin's adverts from the 1950s and 1960s but the blue colour for "Butlin's" makes it unusual. Indeed in the vast majority of cases the name was written in red (the very colour of the jackets worn by entertainers and stewards). The website of the Daily Telegraph has another rare example of an advert from the 1950s in which blue was used.
Even though most of the second line has disappeared, the last letters make it easy to tell what was written there. However the final line is a bit of a mystery.
