Could be. I don't have an 8" label like it to compare it to but I'll google one later and see.My best guess is it was larger but broke, so the label was pulled off, the break sawed straight and label reattached.
I may be wrong, maybe they ran out of 4" labels so they slapped an 8" label on one, but I've seen a handful of broken washita's (none that clean) where the label was preserved.
