In Washington, there are lobbies for everyone and everything -- from airline pilots to film actors. No surprise then that there is a political action committee for the visual arts. Called Art PAC, it was created to fight cutbacks in federal support and to lobby for change in tax codes that limit "creators to a cost-of-materials deduction" when they donate works to a museum, gallery or library, explains director Bob Bedard.

Tomorrow, Art PAC will host its third annual fundraiser -- Political Art '85 -- from 5:30 to 8 p.m. in the Hyatt Regency Hotel, 400 New Jersey Ave. NW. The group is requesting a $25 donation at the door.

On hand to greet and meet will be cartoonists Jim Borgman of The Cincinnati Enquirer, Robert Grossman of New York magazine, Dave Seavey of USA Today and Paul Szep of The Boston Globe. Jeff MacNelly, the Chicago Tribune cartoonist who designed this year's theme poster, will not attend. Works by these and other cartoonists -- Jules Feiffer, Al Hirschfeld and Pat Oliphant among them -- will be for sale at prices ranging from $100 to $1,800. Art PAC also commissioned Washington artist Lisa Lichtenfels to create "half life-size" soft sculptures of President and Mrs. Reagan, Eleanor Roosevelt and House Speaker Tip O'Neill.

"They're kind of like Raggedy Ann dolls," says Bedard, who adds, "This is the first time we're doing sculpture; generally it's always been flat, two-dimensional work. I've made the decision to only sell the Reagans as a couple."

The Washington Convention Center's Arts Committee continues its efforts to spruce up a utilitarian structure. Last week the committee announced commissions for four more large-scale works for the center's lobby and other public spaces. Seven works have been installed since the center's arts program was announced in March 1984. The four new pieces are: "Crossing," a painting by Alfred J. Smith of Suitland; "Acrobatic Troupe," a sculpture by Joan Danziger of Washington; "Fantasy Facade," a kinetic bas-relief by Alice Lees of Washington; and "Wally's World Dance," a suspended, multifigure, plexiglass work by Walter Kravitz. Installation of the Kravitz piece will begin next month. Center officials expect all four works to be on permanent display sometime next year. Just the Ticket

The Fairfax Symphony Orchestra, innovative and tireless in its efforts to build its audience, has now come up with the Flexi-Pass. It's a booklet of four coupons for the orchestra's subscription series at Fairfax High School. The coupons can be used in any combination: Four people can attend one concert, or two people can attend two concerts, and so on. Once coupon holders know how many seats they want for a particular concert, they simply call in advance to reserve the desired number of seats. The advantage for music fans whose schedules are unpredictable is that they aren't tied to particular performance days for the whole season. A booklet of four coupons costs $40, $28 for senior citizens and students. To purchase a Flexi-Pass, call 821-8118. Walters Gets $25,000 Grant

Baltimore's Walters Art Gallery recently received a $25,000 grant from the Charlottesville-based W. Alton Jones Foundation to develop final plans for a museum of Asian art. The new museum, which will be inside the adjacent Hackerman House, will house 3,000 to 5,000 objects, including the Walters' extensive collection of Japanese lacquers and Oriental porcelain. Hackerman House, built in 1850, is a 22-room Greek Revival mansion that the city gave the Walters in September. The new museum will operate separately, but will be governed by the Walters board of directors.

"The mansion is in wonderful shape," says Walters spokeswoman Michel Pratka. It will open, "hopefully, by late 1986," Pratka says.

Washington's own museum of Near East and Asian art, the Arthur M. Sackler Gallery, will open in spring 1987 in the Smithsonian Quadrangle. News in Brief . . .
