Coakley holds a liquor license for off-site catering that applies to Friday's event, according to Judith Powell, administrative assistant for the liquor board.
In addition to drinks, Coakley said she will be serving food in the beer and wine garden at the Havre de Grace Art Show.
Artists and vendors will be set up Friday night, the Rumba Club will play Latin jazz and food will be for sale outside the wine and beer garden too, Coakley said.
The show is in Tydings Park, and she said the wine and beer garden will be in a peripheral 30-by-30-foot space with one exit and one entrance. Someone would be checking identification at the entry point and issuing bracelets for those eligible to drink, according to Coakley.
Drinking will benefit the show's sponsors. Of every wine and beer sold at the Havre de Grace Art Show, $1 will be donated to Soroptimist International, an organization dedicated to helping women and girls in Havre de Grace and beyond.
The art show is expected to attract approximately 2,000 people and while the show lasts through Sunday, the beer and wine garden would only be on Friday night, Coakley said.
"If you're not doing anything Friday night, join us!" Coakley said after the liquor board approved her proposal for the beer and wine garden. "It should be a fun event."
The Havre de Grace Art Show is held in Tydings Park (300 Commerce St.), and admission is free. It runs from 5 to 9 p.m. on Friday, Aug. 16; and 10 a.m. to 5 p.m. on Saturday, Aug. 17, and Sunday, Aug. 18.
