Picture tapes. I had a collection of 20 or so. A few of them were girly
pictures, but there were several excellent ones. Nemoy as Spock holding
a model of the Enterprise. Neil Armstrong on the moon. My favorite was
the PSA grinning bird over the San Francisco Bay - it was 8 strips wide.
FORTRAN carriage control to cause overstriking. I recently got my
collection read off the magtape.
My understanding was the a photo was scanned at 256 grayscale levels,
and the program let you tune the contrast with 16 gray levels of
different overstrikes, ranging from 4 blanks to M, W, X, @ overstruck.
There's a tool called asa2pdf that can turn the carriage control files
into PDF, but printing on a laser printer leads to a chore with an
office paper cutter and lots of staples and scotch tape. I put one
together of SAN FRAN as a parting gift to a coworker at my retirement
luncheon.

As an undergrad in the early 1980s, posters made from line printer
strips were popular. Character overstrikes were used as pixels and
could be discerned as photos from a few feet away. These filled a
wall in our student office / study area. Given the times & 100% male
occupancy, let's just say the posters wouldn't fly today... Each
poster was multiple strips wide. Does such a program ring a bell?
Ascii art was popular, but I don't recall details on making them.

I wrote one in 83. And several of my fellow
students at college did
this as well. It seemed to be a common thing back in the day.
I've used lots of different banner programs on various systems; I
think even OS/360 had one (well, ours did anyway).
