I have bought and received some magazines that has specialized writing about 50 years of STAR TREK. Between the two that I have bought, 'display until 10/7/16 and display until 2/7/20 have some significant differences throughout the magazine. BUT the one the was reissued display until 5/21/21 is "IDENTICAL" to the 2/7/20 issue except for one line on the front page! THIS IS NOT GOOD WITH ME! TALK ABOUT LAZINESS, IT'S NOT WORTH THE PAPER IT IS WRITTEN ON, ESPECIALLY FOR THE PRICE THAT WAS NOT REALLY WORKED ON! User's recommendation: DUE DILIGENCE!
