Wilson History and Research Center (WHRC) was a non-profit 501C3 charitable foundation that housed a private collection of twentieth century military headgear and other militaria in Little Rock, Arkansas.
The WHRC features the largest collection of military headgear in the world, according to the Book of Alternative Records.
Their website also provides a number of articles written by premier collectors of militaria, giving insight into the world of military headgear.
Finally, the WHRC has published Exotische: Rare Cloth Headgear of the Third Reich and is currently working on future volumes as well as other books.
While not every item in the collection is published on the website, the WHRC continues to update the site daily.
