Jamaica Registration: Postal Stationery Registered Envelopes.
Size F envelopes: sub-types of the blue printing.
Evidence suggests that the printing forme was assembled from at least three separate elements,
any of which could be replaced without disturbing the rest: the printer’s imprint; the R in oval; and
the crossed lines and inscription. Some distinguishing features in one of these elements persist
when other elements alter. Even when the wording of the printer’s imprint changes, some minor
features in other parts of the inscription remain the same. This creates sub-types within some of the
five main types. Some features also occur on envelopes supplied to other colonies.

Islands envelope.
