If you have not had a chance to get out or book tickets, the Hereford museums and Art Gallery is available as a virtual tour online so you need not miss out but you can get a preview until you get a chance to get there in person.
You can still see what they have as Museum Resource and Learning Centre in particul their “Inside Out” video which
“bring the hidden gems of its collections bursting into life”
Perhaps the “Ice Age Herefordshire” exhibition that runs until 31 October 2020 at Hereford Museum and Art Gallery.
