Wanted: Banknote With Unofficial Overprints

hi, guys! i'm looking for banknotes now with unofficial overprints. i was hoping some of you can help me if you got some spare in your collection. one example is this particular banknote with the PNAS jubilee o/p. any one willing to sell, please do let me know. thanks!

If you know where to find or reach him (Albino), he might still have some of those 1 or 2 peso (not sure which denom) Pilipino Series notes with private overprints made by the late Mr. Philip Liao to commemorate the 20th(?) anniversary of his company FEMA, a dealer of cash registers and office equipment.

hi! thanks for the tip. but i'm afraid i don't have the contact info of this mr. albino. i managed to purchase a few unofficial o/p'd notes from a coin store in recto (pic below). i'm still looking for the rest and i am very much interested if anyone here can point me to where i can get them. thanks again!
