Hello, dear ladies and gentlemen!
I have several philatelic materials that the Scott catalogue positions as Stamped Envelopes and Wrappers. But I don't see the corresponding pages with similar instances in Colnect, and I didn't even find such a section. If the Colnect Catalogue needs these materials, please tell me how and in which section to add them? Or how to create a section.
I am attaching a sample of one item (USA)
U10 U5 3c red, buff (’54)
