The T-shirt is available in various sizes from small to extra large and can be bought online here:
The T-shirt's description from the online shop:
This unusual t-shirt, exclusive to the Museum, features a stern and imposing Mandrake King (a human-shaped mandrake root, wearing a crown), and is based on a picture from our Richel Collection.
The Fruit of the Loom t-shirt is white, with the mandrake figure in black, and it also has the Museum's twig wand logo on the back.
Mandrakes are one of the most mysterious and magical of plants, so make a fashion statement and invoke its ancient power!
