They Want to Put It Back in the Crypt

I just learned, from Jill Hasday, a constitutional law professor at the University of Minnesota, that in 1921 Congress 

reluctantly accepted a sculpture memorializing women’s 19th Amendment victory. It relegated the memorial to the Capitol’s crypt and painted over the feminist inscription. The statue stayed entombed in the crypt for 76 years [1997... during the Clinton years]. The inscription is still not restored.

Here's the sculpture:

The three women portrayed are Elizabeth Cady Stanton, Susan B. Anthony, and Lucretia Mott. Whatever criticisms I might have of some aspects of their activism, I agree that they never gave up on the cause.

What was the inscription that was wiped out, even as the sculpture was put into mothballs, like the Arc of the Covenant at the end of Raiders of the Lost Ark? 

Here's an image of it:

Gillian Brockell answered the question on everyone's mind about the sculpture itself:

And if you’re wondering “Why is there a blob in the back?” Well, that’s where the first woman president was supposed to go. More than a century later, it remains unsculpted.

I do love that the creators had enough forethought to leave a spot for a future they couldn't see. That it remains so more than a hundred years later… and we're going backwards, if anything, is something to be reckoned with.
