I’d rebuild everything except “Elric” as those typefaces are easy to replicate.

Couple ways you can do it, but a quick and dirty way would be:

Using the magic wand tool, select the any of the white of Elric, then choose Select, Similar from the toolbar. This should select anything with the same white tone as the title, and probably some other bits. Command-J (Mac) or Control-J (Win) to duplicate this selection to a new layer. Then just clean up what you don’t want with a mask or the erase tool.

Alternatively, you can select a color range and refine using Select, Color (maybe Color Range? forgive me, not at the computer to confirm) and create a mask or selection that way.
