This small exhibition at the Frans Hals Museum in Haarlem, North Holland, is a gem. Looking in detail at the restoration of a single painting, The Banquet of Members of the Haarlem Calivermen Civic Guard (1583) by Cornelis van Haarlem, it gives new insight into the painstaking process of art conservation.

The painting had hung for many years in the guards’ HQ where it had become damaged, probably by the swords and lances of the men. The museum’s conservators worked for three years to restore it to its former glory. Van Haarlem was one of the artists who inspired portrait painter Frans Hals, after whom this gallery is named.
