Remember when magazines would include floppy discs or, later, CDs? I have a few mini CDs, I think one came from a magazine. [There are 19,253 mini CDs listed on Discogs. https://www.discogs.com/search/?format_exact=CD&format_exact=Mini This would make a good collection] Has anyone seen a microSD card included with a magazine or a book? It seems to be very difficult to google.
