The bull is one of the symbols of St. Sylvester, and it refers to a story that he resurrected a bull which had been killed by what some versions say was a magician, and others say was simply someone of another religion.
The truth appears to be that it was a Rabbi called Zambre, or Zambres, or maybe even Zambri, and he said he would prove his strength with a miracle, he whispered "Jehovah" in the bull`s ear and the bull fell over dead. Then Sylvester whispered "Christ" in the other ear and the bull sprang to life. And Zambri and his followers were converted and allowed of themselves to be baptised.
This is possibly why St. Sylvester is the patron saint of domestic animals, though to me that phrase sounds too much like pets. Perhaps it ought to say "domesticated" animals?
This is an interesting set, which you can tell was issued during the First World War, for it contains shadowgraphs of "A French Soldier" in his characteristic kepi and "The Kaiser" in his pickelhaube.
My earliest note of this set is in the London Cigarette Card Handbook, issued in 1950, and this is where code H.466 would have originally taken a collector. However if you compare the two, there are some differences. Their listing says
H.466. SHADOWGRAPHS (titled series). Fronts in colour. Issued by Smith. Numbered series of 25.
A. "Glasgow Mixture" back
B. "Orchestra Cigarettes" back
C. "Pinewood Cigarettes" back
D. "Square Thick Black Tobacco" back
E. "Studio Cigarettes" back
We never produced a reference booklet to the issues of F. & J. Smith, though we planned to, intending to combine them with another Glaswegian, Stephen Mitchell. Therefore we first listed this set in our original World Tobacco Issues Index, as :
SHADOWGRAPHS. Sm. Nd. (25). 7 backs, with I.T.C. Clause
A. Glasgow Mixture. Mild, Medium & Full
B. "Orchestra" Cigarettes
C. "Pinewood" Cigarettes
D. "Pinewood" Mixture
E. "Squaw" Thick Black Tobacco
F. "Studio" Cigarettes
G. Sun Cured Mixture
If you look at the cards, brand E in our listing is correct, it is "Squaw". But it is an elusive brand, and it looks as if you will only find it on the backs of one other set, that being "Battlefields of Great Britain".
This listing is identical in our updated World Tobacco Issues Index.
