The Washington Project for the Arts (WPA) is putting together a catalogue to commemorate what it calls "an illustrious decade of presenting contemporary and experimental art." Don Russell, director of programs, and Lynn McCary, associate director of programs, are organizing the project, which they say will most likely take the form of a "newspaper tabloid."

This potpourri of WPA's highs, lows and in-betweens over the past 10 years will include everything from reminiscences to artworks and creative writings -- "the thoughts and memories of things that went on here," says McCary.

Russell and McCary are researching 10 years worth of files and hope to edit the catalogue in December and January, with a tentative publication date of February. Price of the catalogue has not been set.

The two hope to get help from area artists once the project is past the planning stage. "Right now, we're putting out feelers for information and volunteers," McCary says.

The catalogue will be as comprehensive as possible, McCary says. It has been a richly varied 10 years: Few, for instance, have forgotten "A Bird's-Eye View of 77 Artists" from 1977. No doubt some of the reminiscences will focus on two of the 50 Art Site projects the WPA has sponsored, like Robert Wade's 1979 "Largest Cowboy Boots in the World" at 13th and G streets NW, and Nancy Rubin's untitled 1982 sculpture of electrical appliances pieced together in the shape of a tornado, at a vacant lot across the street from the Watergate complex.

It's an interesting concept: billboard art. Many artists would commit high crimes for the kind of exposure available to the winners of "On a Grander Scale," the billboard art competition cosponsored by the Maryland-National Capital Park and Planning Commission and Rollins Communications Inc. The winners -- Jayne deSesa of Baltimore, D.A. Neace of Arlington and Richard L. Dana of Washington -- will certainly get a grand display: The billboards are 14 feet by 48 feet. The works are to be unveiled tomorrow at three sites in the metropolitan area: 9414 Georgia Ave., Silver Spring; a half mile north of Fairfax Circle on Lee Highway, Fairfax; and at 4320 Bladensburg Rd., Cottage City. The displays are part of a two-month pilot program that runs through Dec. 10. The works were selected from more than 200 submissions by Patterson Sims, associate curator of New York's Whitney Museum of American Art. Arts, Etc.
