The ultimate resource about Explorer 12 on the net and probably anywhere is Joe Lang's blog Explorer 12. Its great masthead is featured below.
I came across Joe's blog when it first started and our very own Bill B contributed many items to Joe's growing archive of toys and merchandise.
Sadly dormant for some years, Joe's site remains the number one source of information on the range including variations of the toys from around the world, always a fascinating subject for collectors.
Today's celebration on MC is inspired by Joe's blog and hopefully rekindles the explorer flame in some small way.
