A private view is a special viewing of an exhibition by invitation only, often an art exhibition and normally a preview at the start of a public exhibition.
[1] In the United Kingdom, a private view is generally open to all visitors.
Typically wine and light refreshments are served in the form of a reception.
If the works on show are by a living artist, it is normal for them to attend the private view.
Artworks on view are typically for sale.
