Yeah, only one source for this stuff. Batches differ so you might get a different variation from a different distributor and some batches might be closer to the old stuff but I have yet to see any that were spot on. Nearly impossible to seamlessly match old with new, although a whole set rewrapped together generally will look fine if it is a decent looking batch of wrap.
The other option are the scanned versions by Bumwrap and Walopus. I've only seen the Bumwrap version in person but it struck me as being a closer match to vintage than any recent batches of the 60s style OBP.
