Group portrait of William Sachtleben (3rd from L) with his Humber bicycle and an Acropolis guard, Thomas Allen with his bicycle and an Acropolis guard, and a 5th man on the L, posing on the spot where the statue of Athena Promachos once stood. The 2 guards wear traditional Greek dress including a white pleated foustanella. A panoramic view of Athens is visible in the background.
This photograph was most probably taken in 1895, when William Sachtleben was in Turkey to investigate the disappearance of cyclist Frank Lenz who had last been seen near Erzurum. Notes accompanying negatives indicate that during this trip, Sachtleben was in Bursa and travelled from Trabzon to Erzurum. Sachtleben's 1891 photographs of his bicycle tour across Asia have a circular format.
