[3] In the 1900s, it was frequent that he wrote contributions for the Albumes de Minerva, official proceedings magazine of the Fiestas Minervalias, main propaganda event of president Estrada Cabrera.

[4] However, the author of the lyrics of the National Anthem was still in the dark; between 1896 and 1910, Guatemalans were intrigued about the anonymous contributor that won the contest in 1897; but the enigma was over when Palma Lasso -already in his death bed- confessed that he was the famous «Anónymous»; he had not signed with his name given that he was part of the jury in 1897.

[3] His funeral took place at 10:00 am on 3 August; doctor Luis Toledo Herrarte pronounced a speech in representation of the government and Arturo Ubico Urruela, president of Congress, spoke about the terrible loss and how his adoptive country had loved the poet very much.

[3] The next day, 17 April, in a ceremony in Congress, colonel Alfredo Lima and doctor Aureliano Sánchez Arango, pronounce a eulogy of Palma Lasso, and stressed the love that he had for his adoptive country, Guatemala.

Immediately after, his remains were lifted by the Secretaries of Education of both Cuba and Guatemala, doctor Sánchez Arango and Héctor Morgan García, respectively and by the President of Congress and the Secretary of Foreign Affairs of Guatemala, Manuel Galich and the general public sang the original Guatemalan Anthem lyrics as they were written by Palma; then, the urn was placed on a military jeep and transported to La Aurora International Airport escorted by Army Cadets.

Thousand of children with both Guatemala and Cuba flags walked alongside the urn until it was placed in the Hall of the Lost Steps and the government declared national mourning on 17 and 18 April.
