A fax featuring her favorite cartoon character - - Maxine, the bitchy, old Hallmark lady.
Correction: It's not a cartoon. It's a "funny." Because on the subject line of her fax coversheet, Mama wrote, "Maxine funny."
Since my mother doesn't usually talk like Frankenstein, Tonto or Captain Caveman, I assume that the verb of this sentence isn't missing.
Therefore, "Maxine" is describing "funny."
Sort of like when my grandmother used to call my comic books my "funny books" back in the day.
Anyway, also on the coversheet, my Mama has written, "I thought of you on this one."
The faxed copy of the "funny" has Maxine sitting on a bus or subway train seat.
The caption reads...
"The only thing wrong with public transportation is that it involves the public."
