On the next pages you will find old pictures and picture series. Most of them are related to bicycles, others simply recall a time when daily life was so much different from our life that it may be called a different world.      A substantial part of these photos is courtesy of Loes Peters and Patrick van Griethuysen. On their homepage, you will find many more old photos. Furthermore, I am indebted to Gerlof Langerijs for his contribution.      If you have any questions, remarks or contributions connected with this photo gallery, please mail me.   Gallery 1: Various pictures from the twenties and before.   Gallery 2: Various pictures from the thirties; place and time are mostly unknown.   Gallery 3: 1937 cycling tour of two women from Holland to Belgium.   Gallery 4: The same two women on cycling holiday in 1938 in the Dutch province of Northern Holland.   Gallery 5: More pictures from family albums.   Gallery 6: Pictures of cyclists from 1939.   Gallery 7: Some pictures from the fifties.   Gallery 8: Photos from England (by courtesy of Peter Stray).
