Last summer, art history of the recent past came alive when the first-generation members of Spark Gallery, Denver's oldest artists' co-op, were brought together in the fabulous Twentieth Anniversary Celebration exhibit. Back in 1980, these aging hippies -- among them Andy Libertone and Paul Gillis (the official founders of the group), Clark Richert, Margaret Neumann, George Woodman, Marilyn Duke and John Fudge (who died late last summer) -- were already key figures in the local art scene. All played a significant role in the development of contemporary art in Colorado, and many still do, as does their still-thriving co-op (though none of the originals have remained involved with the group). For the twentieth-anniversary show, these artistic communards each brought out an old piece and paired it with a new one, for an intriguing glimpse of Denver then and now.
