This came with a box of beermats I bought back in the 1980's.The seller thought it was a beermat but it is more likely to be a free gift, a novelty to keep children entertained making the different heads. A means to advertise the name 'Frisby's shoes'. My guess is it dates to the 1950's/60's. I probably paid a few pounds for the box so it probably cost me a few pence as part of the purchase. I've never seen another one so it is probably really rare, and still worth what I paid for it!
