Botanical Art

I read of the recent opening of the Shirley Sherwood Gallery of Botanical Art at Kew Gardens.

The "first gallery in the world dedicated to botanical art and open to the public all year round."

It will exhibit precious works of art from the collections of the Royal Botanic Gardens, Kew and Dr Shirley Sherwood, many of which have never been on public display before."

I wonder if it is the real thing. If it has any Marjorie Holmes.
