I can remove the black background for you no problem. I'll put a straight version up first and follow it up with a verson that has some more elements to make the writing stand out a little more on a white background. Would black lettering (the bank in Millbank) be to strong for you?
Again with this one, I've enlarged a little for ease of viewing and coloured the tag line. On the off chance, i've added a little bloom to the text to see how it looks. Feedback welcomed.
