Micheal found it on eBay of course and decided it was something I would love since I've been embroidering a lot lately :)
It's an embroidery pattern for the Coldstream Guards badge, which is a regiment he collects.
It comes with two different sized transfers and has directions for stitches and colors.
It's probably from the time around WWII, though I really just guessing there. I just love that it's approved by the War Office! :) I think I'll make myself a handkerchief with the small one in a corner, though I will trace the design rather then heat transfer to preserve the kit.
