A billboard promoting the Louisville Slugger Museum prompted a barrage of angry letters, phone calls and e-mails - from Louisville-area needlepointers. The concept under fire depicts a 90-year-old baseball bat with the headline, "More old bats than a needlepoint convention." Red7e, the agency responsible for offending not only local needlepointers but embroiderers and other related hobbyists, was braced for some negative feedback when the board went up, but the staff was surprised by the shrillness of the response. "We didn't think it possible to really stir up the needlepointing beehive," says Dan Barbercheck, Red7e's creative director. "But they told us where to go with our old bats." The fact that the National Embroiderers Association has headquarters in Louisville surely didn't help matters. Conceding, in its own way, after three weeks of protest, Red7e altered the board - the headline was spray painted, barely obstructing all words except "Old bats."
