Britain's most spectacular commemoratives, No35: 1977 Racket Sports 11p

Another successful approach to suggesting frenetic activity can be seen in a set of four stamps on the theme of racket sports. None has more energy than the design showing squash, which would give even the uninitiated a good idea of what the sport is about.

Two silhouetted players are shown part-way through a rally, and stretching every sinew to win the point, with the route the ball has taken shown by a maze of sharply angled dotted lines.

Design: Andrew Restall.

Printing: photogravure by Harrisons.
