National Geographic Magazine from 1998

Here you can see some National Geographic Magazines I bought in a second hand store.
In the store there were about 100 magazines in a crate, and I picked out the most interesting one’s.
They all are in the English language.
One of the magazines is from 1998 and has some 3D images in it. ( from Mars and from The Titanic)
It also contains two carbon 3D glasses.

” It was an unprecedented publishing effort to include these glasses in all 9.5 million copies of this month’s magazine, But I’m convinced they’re the only way to do justice to our coverage of two remarkable feats of human adventure: The Mars Pathfinder probe and the R.M.S. Titanic exploration.” – Bill Allen, NG August ’98
