So the first clue was the name of the team - that being Aberdeen. And the reason is simply because they are a city with a harbour, and harbours are places that are popular with those on our next clue card ...
But there is also another link to Aberdeen with our next clue card too, so read on.
These first appear in our reference book to Ardath, RB.6, originally published in 1943, where they are described as :
Sept. 1936. 165. PHOTOCARDS. SERIES "D" (titled series). Size 3 1/2" x 2 1/4". Numbered 1-165. Real photographs of Football Teams of Scotland, toned black and white, glossy finish, titled, white margins. Backs printed in black with descriptions with "D" at bottom right. Issued with "Kings Cigarettes". Expanding Albums, price 6d., were issued.
It also tells us there are differences between the captions on the front of the card and the back in some cases - and gives a list. However, in most cases this is simply that on the front of cards 10, 15, 16, 29, 59, 93, 131, 146 and 163, the initials "F.C." follow the name of the team on the front title, but on the reverse of the card the words "Football Club" appear instead. The only exception is card 20, which is "Aberdeen City Police Club (Football Section)" on the front and "Aberdeen City Police Club (Football Sec.)" on the reverse.
In our original World Tobacco Issues Index, none of these changes are mentioned and the set is simply described as part of a long list headed "PHOTOCARDS - Numbered Series" as set "4. Inscribed "D". Football Teams of Scotland. (165)". However this gives us our first card code, because the Ardath booklet does not number the sets, only list them in alphabetical order.
There is a slight difference in our updated volume, but only to the header, which reads :
"PHOTOCARDS - Numbered Series. Md. Black and white photos. Nd. Many cards found overprinted in red-brown : "Packed with Ardath Kings - 10 for 6d. - The Longer Cigarette."
The text describing the cards remains the same.
