While memories of last weekend's Minnesota Women's March are still fresh, the state Historical Society wants to collect them.

They posted an appeal Thursday asking people to submit photos or items from Saturday's march on the State Capitol, which drew a crowd estimated at nearly 100,000.

That makes it one of the biggest protests in Minnesota history.

The Historical Society says it's "documenting contemporary social activism," and while it can't keep everything it wants to highlight diverse voices, the varied reasons for marching, and the multiple Minnesota locations in addition to the Washington, D.C. march.

How to offer something

If you're interested in offering something to the Historical Society, you have until March 1 to do it.

Email your photo – or a photo of the object you're willing to donate – along with a short explanation to collections@mnhs.org and put "Women's March 2017" in the subject line.

After March 1 the Society will make its selections and contact the donors.

And if you have something that's unrelated to the Women's March, you can always offer them an item by filling out this form. The guidelines the Minnesota Historical Society uses in deciding what to accept are explained here.
