Milk, Milk, Lemonade

[Mark A. Mandel]

I can't figure out what was posted by Sam and what by Barry. My memory
-- childhood in 1950's -- is only of a rhyme, with no remembered
pointing or other reference:

        What's your trade?
        Lemonade.
        Around the corner ice cream's made.

"Trade" isn't common now in the sense of 'business; line of work', and
I'd be surprised to hear it productively from a child or teenager. Was
it current even then? Or does it indicate a possible earlier origin for
this rhyme in various forms?
