The recent story about a DC comic footnoting Pakistan’s language as 'Pakinstanian" reminded me of a similar incident in a 1980s Marvel comic.
The characters involved travelled across the Atlantic by commercial jet and ended up in whatever small British town the plot required them to be visiting. The artist established this by putting a sign in the background of the panel giving the town’s name with the words “International Airport” under it.
I can’t remember which town it was, but I know it was a small enough place that the notion of it having an international airport was utterly ludicrous. This was pre-internet, so I think it must have been a British comics magazine which drew attention to it so we could all have a jolly good laugh at Marvel’s expense.
I want to say this happened in an X-Men comic of the Claremont/Byrne era, but I could very easily be wrong. Does any of this ring a bell? Can anyone help me fill in the details?
