Do I cite the actual place of publication or the most prominent?

I am writing an MLA citation for a book I am using for a research paper. Instructions I have looked up seem to indicate that it is usually best to go with the most prominently featured place of publication. My book says "The Viking Press - New York" in big letters on the title page, but in fine print on the backside of that page it says "Printed in Great Britain by Butler & Tanner Ltd, Frome and London". It feels sensible to go with the UK because that appears to be the actual place of printing. I guess New York was the base of the publisher at the time of publication though.
