Amongst many items that belonged to my wife's grandmother there was a little paper bag full of these little embroidered flower pictures. These came from packets of Kensitas cigarettes in the 1930s. I've found a couple of sites about these. There were bigger versions that came in tins of cigarettes, but we don't have any of those. We have about 30 of the smaller cards. I've not checked if any are rare, but I guess they may be worth a few pounds each. We have thought about mounting them for display, but there is a danger they could fade and they are currently in pretty good condition.
