This booklet, "Cartophilic Reference Book - No.10 : The Cigarette Card Issues of W.A. & A.C. Churchman. - An Official Checklist Compiled by A Committee of the Cartophilic Society of Great Britain" (or RB.10), was edited by Edward Wharton Tigar, and signed off in November 1947.
It was then printed, though we do not know whom by, as a booklet of thirty-six pages, and twenty-nine illustrations - and published as a limited edition of four hundred copies, in 1948, to be retailed, to Society members, at five shillings.
Like all our individual reference booklets, it was superseded by The World Tobacco Issues Index (RB.21), which was issued in 1956.
However we know that after that time these books still remained in stock as when the Cameric Club merged with the Cartophilic Society, this was amongst the books listed as part of a half price offer, so that former Camericans, and new members, could buy one. By that time the normal retail price had risen to five shillings and sixpence, but the offer reduced it to two shillings and nine pence.
