Hargreaves was a creative director in an London advertising
firm when he began to market his potato-shaped doodles in the
early 1970s. The simple figures were given such names as Mr.
Tickle, Mr. Happy, Mr. Nosey, Mr. Greedy, and Mr. Grumpy. These
characters appeared in books, as BBC cartoons, and in a comic
strip in the Daily Mirror. The "Mr. Men" characters spawned
more than 700 products, from T-shirts to food cartons, and paved
the way for a "Little Miss" series, including Little Miss Helpful
and Little Miss Bossy. Together the two series reached worldwide
sales of 85 million volumes and were published in 20 languages.
