The Greater Des Moines Public Art Foundation and the Des Moines Area Regional Transit Authority will unveil the latest public art bus wrap at noon Friday at the Des Moines Arts Festival. The project is part of the Public Art Foundation’s Project Spaces initiative, which places compelling, temporary works of art in highly accessible and visible public spaces. Artist Larassa Kabel’s design will be the fourth bus wrap in the series. The unveiling will be held on 12th Street between Grand Avenue and Locust Street. Arts Festival attendees are also invited to ride the public art bus for a free tour of public art in downtown Des Moines. Tours start at 1 and 3 p.m. and take approximately 40 minutes. The bus will pick up and drop off at the corner of 12th and High Streets, north of the festival.
