These seem to be leaked pictures of the new 10/11 Boca Juniors 105th Anniversary kit made by Nike.
On 3 April 1905, five Italian immigrants gathered in the Plaza Solís, located in the heart of the La Boca neighborhood of Buenos Aires. Esteban Baglietto, Alfredo Scarpati, Santiago Sana, and brothers Juan and Teodoro Farenga founded Boca Juniors, the use of English language in team names was commonplace, as British railway workers had originally introduced association football into Argentina.
The original jersey colour was pink, which was quickly abandoned for thin black-and-white vertical stripes.The legend has it that in 1906 Boca played another team that used these colours, to decide who would get to keep them. Boca lost, and decided to adopt the colours of the flag of the first boat to subsequently sail into the port at La Boca which was the 4146 ton freighter Drottning Sophia, sailing from Copenhagen.
As the boat was from Sweden, yellow and blue were adopted as the new team colours. The first version had a yellow diagonal band, which was later changed to a horizontal stripe.
