Is any of Heinlein's sculpture known to survive? Are any photographs of it available online?

Well, stretching the definition a bit, you could probably spot his heavy masonry work on Google Earth...

Neither his painting nor his sculpture survive. There are some drawings in the Archive, plus practice sheets for Japaneses calligraphy.

Thanks. That's disappointing.

What happened to the paintings and sculptures?

Some were given away. Somesimply never preserved. Working in clay it's easy to destroy a piece

Ginny talked about a painting he did for a friend's birthday, four different views oof the same subjects, in the style of different painters. She vaguely thought that one might be still around the house somewhere, but nothing like that ws found when we broke down her place in Atlantic Beach.
