WAUKESHA, Wis. (AP) -

A public arts project started by Gibson Guitars is expanding this summer in Waukesha.

The GuitarTown project has been in cities nationwide and started in Waukesha last summer since it was the birthplace of guitar virtuoso and inventor Les Paul.

The project involves artists painting playable and 10-foot fiberglass guitars that businesses then sponsor and display. The money goes to local charities.

This summer, the project is adding 15 large guitars and 25 playable guitars, for a total of 25 large guitars and 42 playable guitars.

The new guitars will be unveiled to the public at an event June 7, when Les Paul's son Rusty Paul, the Les Paul Trio and others will perform.

Project spokesman Norman Bruce says last year they raised $105,000 for the local charities.
