I am trying to document two sets? of chocolate cards from Spain. These were done by Amatller. The first is "Motorismo", the second is "Automovilismo".
By using internet translation programs (Spanish to English), I believe the Motorismo set to be from 1927 and the Automovilismo set to be from 1928.
Cards are fairly large (110mm x 77mm).
By using Google Translate, I found one site on the web stating that the Automovilismo set was "probably" 40 cards.
I have now over several years accumulated well over 100 cards. The highest number Automovilismo card I have acquired is number 23. The highest number Motorismo card I have acquired is 15.
So the questions:
(1) Are these considered two different sets, or a single set? (24 + 16 would make up a 40 card set).
(2) How many cards comprise the set(s)?
(3) How close are my dates of 1927 and 1928?
(4) Is there an authoritative reference for Spanish cards?
Here are two fronts and two backs (4 different cards):
