In 1903 former school football team Sława Lwów changed their name to Czarni Lwów, (Czarni being Polish for Black, the club colour). In fact the full name is I. Wojskowo-Cywilny Klub Sportowy Czarni Lwów (First Military-Civil Sport Club Blacks of Lwów). They are one of the oldest football clubs in Poland. What an excellent team photograph.
