Manila-Legaspi 8

A railway post office cancel of the Manila-Legaspi line.

Pigcawayan

The year 2004 in this Pigcawayan Post Office cancel extends beyond the circle!

And notice the different positions of the dates on the two cancellations. So, my guess is that this postmark was struck twice, first for the DISPATCHED cancel and then for the date.

Pigcawayan is a municipality in Cotabato (also known as North Cotabato) province.

RPO cancel

The purple cancel is a railway post office cancel.

The canceller must have been worn out, but I can still make out Tuguegarao!
