|1998: Millennium 1: 1900-1938 (Design - O Frankzen; Engraver - Martin Morck)|
How would we cope without these inventions and who knew, not me, that these were thanks to Sweden. The zip, ball bearing, vacuum cleaner and refrigerator.
|1946: Explorers and Inventors|
The man behind the world's first commercially successful steamboat, Robert Fulton (1765-1815). It steamed along the Hudson River - the 'North River Steamboat'. He also invented the first submarine 'Nautilus' but the stamp designer has gone with a more scenic view of a modern (at the time of the stamp) steam liner.
|2015: Inventive Britain|
As someone who has poor night vision here is something I like, cats eyes. Invented by Percy Shaw who when driving on a dark and winding road saw the eyes of a cat reflecting his headlights. In 1934 he patented his idea and created a company to manufacture them, the rest, as they say, is history.
The 2015 'Inventive Britain' set also featured carbon fibre and the development by William 'Bill' Watt (1912-1985). I think the stamp set is quite inventive too.
