Philippine Komiks On Stamps!
I just found out that the Philippine Post Office released stamps on Philippine Komiks last November. I saw a set being sold at Ebay and grabbed a scan of it from there.

Featured art includes Gilbert Monsanto's cover to Darna #3 , Francisco Reyes' Kulafu, Nestor Redondo's Darna, Francico Coching's Lapu-Lapu, and Federico Javinal and Coching's El Vibora.
As far as I know, they were released only recently so it is highly likely you can still grab a set of this at your local post office.
Astig, Gilbert! You're on a stamp...and in such prestigious company at that. Congrats!
