Hopefully the Linguistics Stack Exchange is the best place to ask my question.
The opening credits of a cartoon called Gerald Mc Boing Boing uses cursive. To me, it looks like lowercase "b"s are used for "Boing Boing". However, the cartoon was released in 1950. Has the way cursive "b"s are written changed since then?
The following screenshots are all from the opening credits of the short. Notice how several "B"s are capitalized differently from the way "Boing Boing" is written.
How would a 1950s audience have interpreted the capitalization?
