As presidential campaigns sweep through Iowa every four years, they leave behind a trail of T-shirts, yard signs and other candidate bric-a-brac.

Now, some of those mementos could end up on exhibit.

On Friday, the Obama Foundation will host an event in Des Moines for former volunteers from Obama’s 2008 and 2012 Iowa caucus campaigns.

The foundation is looking for campaign memorabilia as well as items that have personal significance to former campaign volunteers to be included in the Obama Presidential Center Museum in Chicago. Even anti-Obama items are welcome.

"Though we’re trying to tell the story of president and Mrs. Obama, this isn’t just about them. Far from it. More than anything, it’s about those campaign staffers and volunteers in Iowa," Obama Presidential Center Museum director Louise Bernard wrote in a Des Moines Register column.

The event begins at 5 p.m. Friday at the Isiserettes Headquarters, 2124 Grand Ave. in Des Moines. It is open to anyone who worked on Obama's campaigns and has an item or story to share. Items also can be submitted for consideration online.

The Obama Presidential Center will tell the story of Barack and Michelle Obama — from their time raising a family on Chicago’s south side to the White House. The museum will highlight key moments, including the 2008 Iowa caucus victory that sparked Obama's successful presidential campaign.

The complex will be built on the south side of Chicago and feature a community garden, public library and meeting spaces.
