Handwritten note on lined paper with blue ink text reading 'Don't waste a stamp & reply Put it in the Kitty Good Luck! Christine Peacock'

A handwritten note on yellowed lined paper written in blue ink. The informal message encourages not wasting a stamp on a reply and mentions putting something 'in the Kitty' followed by 'Good Luck!' and is signed by Christine Peacock. This appears to be personal correspondence from the Laker Airways Skytrain letters collection.
