Illustrated Bikes on Stamps
In 1995 Steve Malone published his catalog "Illustrated Bikes on Stamps" with over 2000 entries and over 1000 images (see BS Magazine, page 16).
Their different symbols increased the usefulness to non-English speaking people. Stamps with tiny bicycles are flagged, those which do not show a bicycle (only a cyclist, the word “bicycle” or a velodrome) as well. Also special symbols for perforate und imperforate stamps and sheets, booklets, und panes are used.
At that time the catalog cost US$ 25 - today it is available for free either as a public domain eBook/ePub or as download.
Steve Malone is now retired and has enough time to cycle across the United States. You are invited to accompany him.
