The Huntington museum was the site for a recent meet-up. The grounds have themed gardens (desert, Japanese, etc.) and many statues. There is a library with the largest collection outside of the National Archives, an arboretum with rain forest, rose gardens, and a couple art galleries.
Here are some interior items.
I'm guessing this is a harpsichord, not a piano, because it is from 1773.
Various knick-knacks.
Tapestry.
Little men.
Chairs from 1823. Painting is "Salisbury Cathedral from the Bishops' Grounds", 1823-26, by John Constable.
Ceramics.
Works by Shakespeare and others.
Gutenberg bible (one of two volumes) from about 1455.
"Pinkie" by Thomas Lawrence, 1794. She died about a year later, aged 12, from whooping cough.
"The Blue Boy" by Thomas Gainsborough, about 1770. The artist painted over something already started.
