Towards 1860, the Parisian impresser Lemercier makes colored lithographs titled Buenos Ayres. La Boca del Riachuelo cerca de Barracas, over pictures drawn by the French artist D. Dulin. Two of these lithographs are presently found at the Museo Histórico Nacional, which also houses drawings by P. Mousse, lithographed by A. Clairaux. We can also find other anonymous lithographs about this topic and numerous photographs that register these places between 1900 and 1914.
