It has always been a nomadic monster, roaming the Quad Cities (usually Rock Island) in search of arts patrons. In recent years, it has squatted at The Villa, the McKesson building, and (most recently) the Rocket Theatre.

Now, in its 13th year, it has taken up temporary residence across the river in Bucktown, and it has also mutated. What was once a single-minded creature - all about selling art - has now evolved into something of an entertainer. To its already formidable arsenal it has added magic and improvisational comedy and a haunted dungeon.

It is, of course, MidCoast Fine Arts' Great Mask Halloween Bash & Fine Art Auction, scheduled to start at 6 p.m. on Saturday, October 21, at the Bucktown Center for the Arts (225 East Second Street in downtown Davenport).

Painter John M. Booth, referencing one of his artworks, says, "Hopefully, it'll put a smile on somebody's wall." The odds are pretty good that it will - in his airbrushed acrylic paintings, there's a lot of smiling going on.

In Booth's Fishin, an enormous red fish grins dementedly as he prepared to devour a small black cat. In Tada, a similar fish - emerald green this time - is balanced on top of a cat, who, in turn, stands upon a dog; their smiles indicate great pride at the feat. (Ta da!) In Good Coffee, a balding, middle-aged man looks frighteningly giddy about taking his first sip.

And throughout Booth's works, many of which can be seen at (http://www.masongraphics.net) and at Riverssance this weekend, his figures - human and animal, smiling and unsmiling alike - are painted in bold, vivid colors, a vibrant array of reds, blues, greens, and purples.

At her house, Katie Kiley is drawing in India ink on a wooden vase created by Steve Sinner. Using magnifying-glass headgear and two of the finest-point pens she could find, she's creating eight panels around the vase, depicting scenes from a California town. The naked eye can't appreciate the level of detail, and each panel takes two weeks to complete, she said.

Sinner expects to sell the piece for $20,000, Kiley said, and she's being extremely careful with the vessel. "I have this resting on a down pillow," she said.

Sinner, of course, is among the most highly regarded artists in the Quad Cities, and Kiley notes that he knows what price his work commands. But she is no slouch, as evidenced by two awards she won in the 181st Invitational Exhibition of Contemporary American Art, presented by the National Academy in New York City.

Attendance for the 16th annual Riverssance Festival of Fine Art in 2003 - the first year the event was presented in conjunction with MidCoast Fine Arts - was estimated at about 15,000 people. But last year's festival drew roughly 12,000 attendees, a number that Riverssance Director Larry DeVilbiss admits was well below expectations.
