I would say that Tinghalls and Konig are definitely part of my top 2 for the reasons that you mention and they have many key players from many countries. The others are hard for me either to do the fact that most sets focus on a country / league so that the players are not world class which tends to push us towards World Cup issues... so I understand your inclusion of the Panini WC 1970 and ALFA cards.

Some of my Argentina "contenders" would be the 1925-27 Dolar cards (players inclusions), 1935 Argos cards (beauty), 1936 Los Leyes cards (unique), and 1926 Plus Ultra cards (photographic), 1935 Cabecitas de Ora (see my other post) or the 1946 Olympia cards (is there a most beautiful card set out there?)...

I am also trying to put together the 1888 Circus Girl set as one of the coolest early sets (including GO Smith)...

I will continue to think of this, as it is a great question. Thanks for posting.
