1974 United States 18 Cent NATO 25th Anniversary Letter - Scott #UC49 Unused. Unfolded. I am not an expert. Please see the pictures. This is a representation of the group for sale. If there are variations from this picture, I will sell it separately.  I know shipping seems like a lot, but this is what I am being charged. Feel free to ask questions.  I will combine shipping. See my other items! Thanks!
