There was a thread elsewhere which addressed the question of what such thingies might properly be called as, if I recall correctly, “catchword” was the majority choice.

Some of my fonts include catchwords, but not these particular examples. However, you could try a search at MyFonts.com with the keyword ”catchword,” or take a look at Letterhead Fonts: the /THE/ especially has an LHF kinda vibe…

«THE» is set in Brothers (by Emigre).

The "THE" is Brothers.

Yup:

/AND/ is set in LHF Boston Truckstyle
It was stored in letter /& of the old Type-1 and TTF version of the font,
but I see the latest OTF version has a normal /& glyph...
I don't know

PS: I suppose it may exist as a 'stylistic alternate' in the new OpenType font

Thanks everybody for the help, I really appreciate it!
