How many complete collections of NGM are out there??
Which issues do you have in your collection?
Including the 99 reprints I mentioned, I have a complete collection. 1888 to 1895 are all reprints. 1896 to 1907 are mixed. 1908 to 2020 are originals. I just got the December 2020 newsstand copy, still waiting for my subscription copy.
Sorry, the best way to describe the state of my collection is "organized chaos". I keep meaning to get it presentable but life keeps getting in the way. Maybe some day.
As for the Newsstand copies, I've only been buying them a couple of years, mainly for my Cover Variant research (and because I can get them sooner to read and image).
