flight covers catalog

A slim volume, Flight Covers of the Philippines 1947-1988 is authored by Linda Stanfield.

Copyright year is 1990.
This was published by Fritz Walter Lange of Germany.
Printed in black and white.

Cachets are illustrated (in actual size, I believe) and known quantities are given.
The name of the airline is listed, the flight (whether it's first flight or another), destinations, postmarks, and backstamps.

If known, the names of the pilots are also given.

This is a priced catalog, in US dollars.
Bought my copy in the 1990s from the IPPS bookstore in the US.

IPPS is the International Philippine Philatelic Society.
