1963

Postcard postmarked November 4, 1963.
Inscription on the back reads:

TRANSPARENT WOMAN

A Talking Transparent Woman is demonstrated daily at the Museum of Science, Boston.  Presented by the Mass. Heart Association, it gives a dramatic lesson on body structure and function, showing circulatory and nervous systems and internal organs.  The life-size figure was fabricated at the Deutches Gesundheits Museum, Cologne, Germany.

1998

This looks like the same figure in the 1963 postcard in a 1998 display.
