URBANA — As far as themes go, John David Mooney's newly installed 33-foot-high sculpture just north of city hall won't be alone.

The city of Urbana Public Arts Commission and the Public Art League have issued a national call to artists to submit for a competition sculptures that would be leased for two years and placed in downtown Urbana.

Like Mooney's, the public-art sculptures are to have a tree theme to celebrate Urbana's designation, every year since 1976, by the National Arbor Day Foundation as a Tree City U.S.A.

Selected artists will receive an honorarium of $1,500, sponsored by the Urbana Public Arts Commission. The competition is open to all professional visual artists age 18 and older with public-art experience.

All submission materials must be received by the Public Art League by 5 p.m. June 15.
