This booklet, "Cartophilic Reference Book - No.12 : The Cigarette Card Issues of James Taddy & Co. - An Official Checklist Compiled by A Committee of the Cartophilic Society of Great Britain Limited" (or RB.12), was edited by Edward Wharton-Tigar, and signed off in July 1948.
It was then printed, by Parker Brothers, of St. Albans, in Hertfordshire, as a booklet of thirty two pages, and thirty illustrations - and published as a limited edition of four hundred copies, in 1948, to be retailed, to Society members, at seven shillings and sixpence.
Like all our individual reference booklets, it was superseded by The World Tobacco Issues Index (RB.21), which was issued in 1956.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 eight shillings and sixpence, but the offer reduced it to four shillings and three pence.
RB.12 cites that only RB. 13 (Phillips) forms the balance of the 1948 programme. The “Proposed 1949 programme” is "Nos 14 to 20 (order not fixed) Ogden (moved down from the 1949 Programme), plus the previously quoted Carreras & Boguslavsky, Player, Wills III, Ogden`s “Tabs”, Mitchell & Smith, Ogden`s “Guinea Gold”.
