Punched in the face!
You should know better! The image attached to the Letter of the Month in LXF308 is not of punched cards at all. It is of folded paper tape.
I have attached an image of real punched cards, attributed to use on a DEC PDP9. I do not recall ever working on that model – yes to almost every one of the PDP8 and 11 families, at least one PDP15, every variant of VAX and most Alphas.

The photo is, of course, paper tape. It appears to be six-track, which I’ve never seen. I have used seven and eight-track, even five-track in the early days (1964).

Thanks for the correction John, David and others – you’re obviously absolutely correct. The photo we used doesn’t even look like cards. Not sure what’s going through my brain…
