Porcelanas Pavon Guerrero Sin Hielo. Cat no. HW-128. 500cl capacity - which is just about 1 full pint in English money ;-) Confusingly P.Pavon make 3 very similar vessels. There is a smaller capacity version of this mug called Guerrero Mediano (350cl). And a larger (550cl) version with a separate compartment for ice called Guerrero Hielo. This is the Sin Hielo version (without ice). It's more yellow than green (it looks green because of the thin black lines painted over the yellow). Got 2 of these in a job lot off eBay.
