I stumbled across this clip from season 7 of Sesame Street...
It originally aired in January 1976, so it would've been around the time I was regularly watching, although I don't recall this specific scene at all. But what struck me today was that as Harry walks up to Luis, he passes the normally-open door of Mr. Hooper's Store; however, since it is closed, there are several comic books visible attached to the inside of the door window.
You wouldn't normally see these on the show since the door is almost always left open; I don't know why they would've had it closed here.
In any event, none of the comics are shown very clearly, but I was curious to try to see if I could identify any of them.
It was a bit tricky, but I was able to figure out five out of the six...
Sad Sack #237 (middle left)
Richie Rich Millions #74 (bottom right)
Richie Rich and Jackie Jokers #12 (top right)
Archie #248 (middle right)
Our Fighting Forces #161 (bottom left)
All of these are cover-dated November 1975, so they were probably about as current as you could get when they filmed this. Most of the titles make sense for a kids show in 1975, but I have to admit I'm at a loss about the inclusion of Our Fighting Forces. I mean, it's a DC comic from 1975 so it's not super graphic or anything, but it is expressly a war title, so it seems a little odd that they would include it on Sesame Street. Even just as a background prop.
