The easiest—and maybe the cheapest—way of displaying a giant Philippine map may be to cut it out from a Styrofoam board, mount it on plywood, and paint it. But the marketing group of a shopping mall in Rosales, Pangasinan, wants something out of the ordinary, especially because it is going to be the centerpiece of the mall’s display for today’s 115th Independence Day celebrations. Why not build a giant Philippine map made of oyster shells?
