Design
This is an enamel pin based on a lovely woodblock frog print by Japanese artist Matsumoto Hoji, from the 1814 book 名家画譜 “(Meika gafu”, an anthology of pictures by celebrated artists of the Edo period). I made a couple of very minor changes to the design in order to make him work as a pin, but believe I have preserved his glum, grumpy character. You can see the art which inspired this badge at the British Museum in London, or find more details of it here: https://www.bmimages.com/preview.asp?image=00286082001

Material
20mm hard enamel, black nickel, single pin fixing, butterfly clutch.
His tummy is white but the rest of him is a very dark brown – it’s quite visually distinct from the black nickel in natural light.
