The Newspaper Umbrella
Our neighbor is an affluent inventor whose latest brainstorm, a feasible
umbrella substitute, has been featured in may magazines. As simply as eye
can discern, it is a hard plastic strip, about the size of a ruler, which 
fits comfortably into woman's handbag or man's suit jacket. When a person
is caught in a sudden storm, he swings the plastic strip open in a shape of
cross. Attached to each arm is a clip-like device. Next, he takes the 
newspapers he is carrying and slides it under each clip. Now equipped with
a rigid head covering he can set forth to face the elements.
To the consternation of umbrella manufacturers, it has been enjoying a brisk
sale. If it continues to do well, it could have a pernicious effect upon 
the umbrella industry.
