1931 Dennison's Halloween Bogie Book

Most of these larger form-factor Dennison Bogie Books were folded for mailing, so to find one without the standard center crease is unusual. Given that this was how they were mailed, I don't feel it is correct to consider the fold a condition issue. This example does have a prior owner's name written on the front cover, something this seller doesn't point out.
