This is probably not the back you were expecting, for it is one of the scarcer Australian versions.
In fact this set was issued six times, and is first described in our original reference book RB.11 – The Cigarette Card Issues of W.D. & H.O. Wills Part I (revised) and Part II, which was published in 1948, as :
- 97. 50 SIGNALLING SERIES. Fronts lithographed in colour; backs with descriptive text.
HOME ISSUE, 1911 :-
A. Backs in blue-grey
AUSTRALIAN ISSUES, 1913 :-
B. With "Capstan" advertisement
C. With "Havelock" advertisement
D. With "Vice Regal" advertisement
E. No brand advertised (anonymous issue)
Similar series issued by Player.
However in our original World Tobacco Issues Index this listing is no more, for the parts have been scattered. First up is the home issue, listed in section 2.A, as
- SIGNALLING SERIES. Sm. Nd. (50). See W/97.A ... W62-102
And next, three of the Australian issues, under section 3.A, where they are recorded as :
- SIGNALLING SERIES. Sm. Nd. (50). See W/97 ... W62-236
A. "Capstan" back. Numbered
B. "Havelock" back. Brand issue.
C. "Vice Regal" back.
The problem with this is that it has changed the prefixes, so our set suddenly becomes "A" not "B". As for the anonymous version, that is shunted to the back of the book, with the "Z" numbers, where it appears under "Anonymous Issues (1) - With Letterpress on Back" and sub section 1.B.b, for "Australian Issues. Inscribed with album wording "... at 1/- each through all tobacconists", except ZA3-7 inscribed "Presented to Smokers of these Cigarettes". Small size 67 x 36 m/m, unless stated. Issued through B.A.T." . The description reads :
- SIGNALLING SERIES. Sm. Nd. (50). See W/97.E ... ZA3-6
Lastly, the Player version is recorded under their section 3.B, for "Issues 1923-30. Chiefly in New Zealand, Malaya and Siam. Small size 67-68 x 35-36 m/m unless stated." The description there reads :
- SIGNALLING SERIES. Sm. Nd. (50). See RB.17/179 ... P72-202
