The flag is a white swallowtail with blue upper and lower edges and red OD initials at the centre, sometimes punctuated with periods. A July 1895 Cosmopolitan advertisement shows dots after the initials. Rosanoski considers O130 probably intended to include a dot after O as well; McMillan’s O129 drawing omits the dots while acknowledging punctuated versions.
