[alt-photo] Anthotype show in Washington DC 1990's

[gumprint at gmail.com]

Greetings,

Does anyone recall a show in downtown DC of Anthotypes about 15 years ago?
It may have been at the Library of Congress or the National Gallery. It's
was billed as "the first color photograph". I'm hoping to learn the location
and name of the exhibit in order to track down the accompanying catalogue
and/or book.

Thanks in advance for your help.
