Illustrated Bikes on Stamps
In 1995 Steve Malone published the catalog "Illustrated Bikes on Stamps" with over 2000 entries and more than 1000 images (see BS Magazine, page 16).
A special feature were these checkboxes:
The different symbols increased the usefulness to non-English speaking people. Stamps with tiny bicycles are flagged, as well as those not showing a bicycle - only a cyclist, the word “bicycle” or a velodrome. Also special symbols for perforated und imperforated items are used.
Previously 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 is cycling criss-cross the United States accompanied by his wife and their dog.
It seems he likes the mountains.
You are invited to accompany him.
