OGDEN — Weber State University’s Shepherd Union Building turns 50 later this year, and organizers of an art show are asking the public for help finding historical photos and sketches.

Selected items would be shown in the opening exhibition of the union gallery's 2011-12 season, from late August through October.

"We are hoping that former Weber State art students may have made sketches or taken photographs of the union at various times during the last five decades, either as formal assignments or as personal projects," gallery coordinator Nikki Nicholas said.
