Me too, actually. It's an easy enough assumption, considering most artists working on British work tend to ink their own work.* Those who work in colour would often colour it too, but you're more likely to find a different colourist than a different inker, if you get what I mean.
That's true, but remember this is a family affair, so sometimes he'll help me with inking, colouring, or wathever I need, or even sometimes I'll do everything by myself, if he has work outside.
