A poster featuring Norwalk High School wrestlers posing shirtless in firefighter gear has raised concerns among some parents in the Des Moines suburb.

Parent Danielle Lynn posted an image of the wrestling team poster on Facebook last week, saying it both sexualizes teenagers and is an example of the double standard that exists between male and female students.

"Could you imagine the outrage had a girls’ team dressed in bikinis and taken a team photo?" she wrote. "This makes me so uncomfortable as a parent. ... The sexualizing of children and teenagers needs to stop.”

The post generated more than two dozen replies mostly supporting Lynn's comments.

Freelance photographer Dale Tunender, who was hired by the team to take the picture, is surprised by the reaction.

“They put it together and they decided who was wearing what,” he said. “The boys requested to not wear their shirts. These guys are wrestlers. They are proud of what they’ve done and what they look like."

Tunender, who shoots team posters for other schools, including swimming photos with athletes clad in Speedos, said he's never had complaints before.

"It shouldn’t be that big of a deal,” he said.

Lynn reiterated her objections Wednesday in an interview with the Des Moines Register.

"Some of these boys, I know, are only 13 years old," she said. "And the only girl in the picture, who is a manager for the team, is wearing a T-shirt and jeans, while all of the boys around her are shirtless.”

Norwalk High School Athletic Director Al Lammers said team posters aren’t paid for or approved by the school district or the sports boosters programs.

“Those posters are produced independently by each program," Lammers said. "The revenue goes to offset the cost of producing the posters. They probably don’t break even. The posters are more of a promotion.”

Lammers said he hasn’t received any complaints about this year’s wrestling poster.
