This is fascinating gallery and small enough that you can see all in a relatively short time.
Take the tour. It is well worth it. Our guide was informative and friendly and told us so much that it enriched our visit.
There is such variety in the “portraits” - both in the subjects and the way the artists have represented them. Interesting perspectives and insights into a range of individuals.
The staff seem to go out of their way to help and the parking is good.
