1928 Unrecorded Paquebot Boxed Notice

1928, NOVEMBER 8: ILOILO to MANILA
West Visayas Mission, Iloilo, Panay, P.I. cc cover with handstamped purple PAQUEBOT
and boxed-in auxiliary marking on verso. 2c Rizal cancelled upon arrival in Manila.

Fig 1: Boxed-in auxiliary marking on verso,
measuring 87 mm x 32 mm.

This is the first time that I have seen this boxed-in marking and I think
this has yet to be recorded the best authority to validate my assumption
is IPPS America. Text and size very different from the common one found on Paquebot
covers originating from Cebu, Davao and Zamboanga (Figure 2).

Fig 2: Measuring 85.0 mm x 19.0 mm.
