So I'm attempting to identify a font that appears in the cover graphics on the covers and spines of original editions of Everyman's Library. These appeared in the 1906-1928 period, incorporated into graphics designed by Reginald Knowles. I've tried to find a specific font but to no avail. It is possible this was a font designed specifically for the graphics, or a combination of more than one font. On the other had, it may be well known, but I can't figure it out, and have not found any information online. I have scanned some of the artwork; the artwork looks a little rough (gold gilt impressed into a leatherette surface), though it is possible this was done intentionally for a rustic look. I've isolated a few lines end removed most of the surround artwork. I'm looking to clean up the artwork and lettering as part of a project I'm working on, and any help identifying the fot would be greatly appreciated.
