Wallpaper (1950s bus ticket design) to finish job

[LMitchell]

I have run out of wallpaper .... If anyone has any left overs of this 1950s Festival of Britain bus ticket wallpaper they'd like to give away or sell on, I'd be very very grateful. I originally got it from the London Transport Museum but it is now on sale in John Lewis. However, I only need a small amount to finish around the window (see photo) so am trying to avoid having to buy a whole new roll. It's the yellow and grey version. Fingers crossed someone will reply!
