Part of my regular scouring includes the usual junk at Govdeals.com - sometimes there's something local
that's being offloaded for a song that's useful for flipping or parts.
In all the time I've been look there, though, nothing has come close to the fantasy listing I saw:

SPEAKER, SPEAKER HOUSING FROM THEATRE CALLED VOICE OF THE THEATRE - GovDeals.com

To complete the fantasy, the poster has even hinted strongly that they don't know entirely what it is they have...

Please someone in AL give good money for this beauty, and send us photos of the careful, lovely splendor to which
she is returned.
