Your trinket box is a well known example of Heubach's work. I
have seen it in several sizes. Heubach was famous for making
piano babies and statues of children, as well as heads for dolls.
I have seen these boxes range in price from $550 to $1,500. The
prices on Heubach pieces has risen sharpley in the past few years.
Yours is a medium sized example, so I would guess (and it really
is a guess) between $500 and $1,000. U.S.
Hope this is helpful.
