Calder Caps


Philadelphia is a city known for its recent procession of world champion athletic teams: the Eagles, Villanova University, and the Phillies. Phanatic Philadelphians dawn the baseball caps these respective teams to show their championship pride.

Lesser known, however, is the royal family of Philadelphia’s artistic champions – the Calders; three generations of great Alexanders that shaped Philadelphia’s artistic and cultural landscape starting in the 19th century. The last in the ancestral line, Alexander “Sandy” Calder changed the course of modern art with his signature kinetic sculptures.

On Sandy Calders 121st birthday, we introduce a new variety of baseball cap; one which celebrates the mark of Philadelphia’s art MVP, Sandy. Available in Cream of Calder, Brick, and Cauldron Black. One size fits all!

Calder Caps is a collaboration between
Nate Harris & Ryan Strand Greenberg.
Made in Philadelphia.
