Joe Rubinstein and Josef Rubinstein - Creators

It's the same guy.

When you get round to this one, you should also remove Rubinstein and Josephn Rubinstein. Thanks.

which is his common naming?

I think Josef Rubinstein, but I'm open to Joe as well. I used to be decisive, but now I'm not so sure.

Over the years I've mostly seen it as Joe.
