Here is a very nice set of 4 1970's NIA commemoratives. These were made in various numbers but not very many of these seem to pop up! There's bright red, sky blue, goldenrod and light lime green. All are mint condition and there is also an original certificate of ownership that comes along with them. Very colourful and very collectible NIA commems! Years are:1975-1976-1977-1978. First mail to me.... $120 shipped in USA for the set. Canada and other countries I will assist with shipping. Package will be over 5 LBS well packed. Now $80 + shipping.
