In 1909 the Centenary Commission hired Lola Mora to realize longed monument in the framework of the centenary celebrations planned for city. Should be noted that Lola Mora project for the flag memorial is the only thing links the festivities in the city with what was being developing in Buenos Aires.
The tucumana artist was already known within the art field from her great monumental installations in public spaces. Although the Flag Memorial appears as a desire of the sculptor since 1903 the Commission is formed, the moment of its concretion coincides with her political helplessness. The truth is that the monument should be completed by 1911, however between 1915 and 1916, when the Centennial Commission had become into the Ministry of Public Works, the problems concerning the payment of the last two installments of the amount stipulated in the contract continued, despite the fact that all terms of the projected works for the Centenary were overcome. In 1919, after an arbitration that took care of evaluate the conditions of that was produced in Italy by the artista, a conflict with Department of Architecture took to ask the rescission of the contract. The injunctions extend until 1923, while the works were still there. After the long-awaited arrival of them to the city, in 1923 the Municipal Commission of Fine Arts issues a statement to the mayor stating that the result doesn’t correspond to a work of art, but seem a work of “simples marble workers”. Hereinafter, the Pro Flag Memorial Commisssion, in his meeting held on August 3 1925, decides to ask for the rescission of the contract with Lola Mora and promote the building of a new one.
