When can we get a Marmite 'n' anything stand?

For convoluted reasons I don't feel like explaining right now, Nutella and Marmite are closely associated in my psyche (suffice to say, their main roile is to be spread on bread and some people like them, and some don't).


I found this rather magnificent picture of a Nutelleria stand in Italy which sells all kinds of things spread with Nutella:




When can we get something similar but with Marmite, not a Nutelleria but a Marmitery?
