Condition: Rare special printing mint stamp with a color copy of the original PF cert for which this is the upper left stamp from the block of 4 stamps as shown… I have included a reference regular printing for comparison… I have added a nice selection of many stamps to my store. I fondly remember going to stamp shows as a child, enjoying going through counter books where I could pick out the’ideal’ stamp for me. The days where local stamp shows would allow this experience are few and far between. I have attempted to re-create this by listing selected stock which you can pick from. Feel free to contact me at.
