Ceremony for the President of Mexico, Isthmus of Tehuantepec, Mexico, 1905.

MEXICO - AUGUST 31: President Diaz passing a guard of honour during his visit to the Isthmus of Tehuantepec, Mexico, in 1905. President Porfirio Diaz (1830-1915) ruled Mexico, effectively as a dictatorship, from 1876 until the Mexican Revolution forced his resignation and exile in 1911. Between 1899 and 1907, the British construction firm S Pearson & Co built a railway line across the Isthmus of Tehuantepec, connecting Mexico�s Gulf and Pacific coasts, as well as port facilities at either end of the line.
