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.
Photograph of William Sachtleben [L?], on a Humber bicycle, and Basilios Kapsambelis, on a bicycle, in costume for Carnival in Piraeus. They are in the Municipal Theater Square with the Greek Orthodox church of Saint Constantine and Helen in the background. The church is located at Karaiskou 109.
