This is rather an odd card because whilst the others in the set show girls holding their actual national flags, this one is just a streamer-like pennant.
Our card has the United Services reverse, with a reproduction of a packet of cigarettes featuring Field Marshall Lord Roberts, familiarly known as "Bobs", but, with his full title, as Field Marshal Frederick Sleigh Roberts, 1st Earl Roberts VC, KG, KP, GCB, OM, GCSI, GCIE, VD, PC, FRSGS (30 September 1832 - 14 November 1914).
These cards are listed in our original Wills reference book part three as being 60 x 37 m/m, lithographed in colour, and issued about 1910. They were issued in the Channel Islands and in other areas with British garrisons. You can see the packet in colour on flickr. Strangely enough, possibly because of its connection to garrisons, this packet is actually one of the most reproduced small items for military re-enactment groups - you can see one, courtesy of one of the leading dealers in this field at Tommy`s Pack Fillers and it also shows the back of the packet, which is similarly military in design.
This is a good set for a type card collector, because you can find it also by Wills in many countries including Australia (branded Vice Regal Cigarettes) and India - then it was also produced for Lambert and Butler - and for John Player - or you can find it with no brand or maker, and this was issued in Canada.
And if that was not enough it was also produced as medium size cards by British American Tobacco.
