Out of interest, could anyone tell me what this organisation is? I ask because an individual on a Facebook pin group is selling cheap pins in bulk, and says " All have been authenticated by the IMPaS group ". Having collected pins for over twenty years, I'm intrigued when I see something that I've never heard of. By the way, I did do an internet search, and came up with a number of companies using these initials, but none were pin related. Thanks!
