We believe these are two Wolseley touring cars racing along Chesterfield Avenue in the Speed Trials that were held at Dublin's Phoenix Park on Saturday, 4 July 1903 (110 years ago today). Unless, of course, you know different...
Not fantastic quality, but given speed and presumably excitement, the photographer J.J. Clarke can be forgiven?
