Philippines, Mostly used. Chaotic volume from early Spanish imperf colonial issues, through young heads with several dozen on to the US Administration with well over 50 stamps to 50cts o/ps, as well as further early 20th century also by the hundreds inc high values to 10 pesos. Lots of back of the book inc O.B. o/ps, Victory o/ps and much more, huge potential for the specialist. (Image1)
