Spot the difference street signs 1

What interests me about these signs is that although they appear to date from the same time there are subtle differences. They are situated opposite each other at the junction with Bayswater Rd.
Presumably the lower one is slightly narrower to fit in the space between the pillars but why two lines for the leading to ... section and why is Bark Place underlined?
(And is it actually interesting, I find myself wondering...)
