Credit must go to Sarah from The Cake Tin and Jo from Ciccio.

Just as I was trying to think of an idea for a cake for the retirement party
for the head of the lab at the hospital I work at, Sarah posted photos of
her Einstein cake! Eureka!! Just what I was looking for!
Philip retired after 47 years – What an achievement!
