National Heroes Souvenir Sheet
9 February 1944

Handstamped with First Day of Issue cachet cancel but with mssing black imprints (text).
Inverted Characters on Censor Mark
5c on 6c Provisional Issue (First Printing)
Surcharged on 1939 Allegory Issue
1 September 1942
The regular and correct order in the second row of the characters
'Ken Etsu Zumi' meaning 'censored'.

The oval money order marking is merely an embellishment.
So with the hen and the cow.

Cover below: A Boustrophedon. The second row of the characters are inverted.

 
Is it really an error or a printer's waste
pilfered from the Manila post office vaults
and cancelled to favor?
