NEW YORK - Some Broadway heroines are rolling up their sleeves and posing in a familiar way to support National Women's Equality Day.

Kristin Chenoweth, Laura Benanti and Patina Miller were some of the women Wednesday on Twitter or Instagram striking the classic Rosie the Riveter pose.

Others included the leading ladies of "Hamilton" -- Renee Elise Goldsberry, Jasmine Cephas Jones and Phillipa Soo -- and the trio of women heading the "The King and I" -- Kelli O'Hara, Ruthie Ann Miles and Ashley Park.

It's an attempt to bring attention to the fact that there's no Equal Rights Amendment and to help it get reintroduced in Congress.

Other participants included Beth Malone and Judy Kuhn from "Fun Home," composers Cyndi Lauper and Sara Bareilles, and actresses Laura Osnes and Stephanie J. Block.
