Here is a question about this article: A month after the Spanish Civil War began in 1936, several players from Barcelona enlisted in the ranks of those who fought against the military uprising, along with players from Athletic Bilbao. On 6 August, Falangist soldiers near Guadarrama murdered club president Josep Sunyol, a representative of the pro-independence political party. He was dubbed the martyr of barcelonisme, and his murder was a defining moment in the history of FC Barcelona and Catalan identity. In the summer of 1937, the squad was on tour in Mexico and the United States, where it was received as an ambassador of the Second Spanish Republic. The tour led to the financial security of the club, but also resulted in half of the team seeking asylum in Mexico and France, making it harder for the remaining team to contest for trophies.
What is the answer to this question: What was club Barcelona considered to represent when on tour in 1937?
****
So... Second Spanish Republic

Here is a question about this article: Shorter, black-and-white daily strips began to appear early in the 20th century, and became established in newspapers after the success in 1907 of Bud Fisher's Mutt and Jeff. Humour strips predominated at first, and in the 1920s and 1930s strips with continuing stories in genres such as adventure and drama also became popular. Thin periodicals called comic books appeared in the 1930s, at first reprinting newspaper comic strips; by the end of the decade, original content began to dominate. The success in 1938 of Action Comics and its lead hero Superman marked the beginning of the Golden Age of Comic Books, in which the superhero genre was prominent.
