|NASA'S Messenger Probe Spots Smiley Face on Mercury|
From the Associated Press wire for April 13, 2001 (www.boston.com/news/daily/13/smiley.htm):
WORCESTER — Harvey R. Ball, whose simple drawing of a smiling face on a yellow background became a cultural icon, died Thursday after a short illness. He was 79. Ball, who co-owned an advertising and public relations firm in Worcester, designed the Smiley Face in 1963 to boost the morale of workers in two recently merged insurance companies.
