I have a pack of the above in a blue box with London scenes on the rear. The tax wrapper is intact and has been stamped, I think by Woolworths. From the style of the box my guess is these are from just pre or during WW2. I have absolutely no interest in keeping them as they probably came from my parents, both of whom died in the 1970’s and have resided in a memorabilia box since then. My guess looking at eBay is they are worth circa £25.
