Billboard on the east side of 7th Avenue between 47th and 48th Streets (near Times Square). It was just above a theatre I was working in.
In case you can't read it, it says:
" Hi Steven,
" Do I have your attention now?
" I know all about her, you dirty, sneaky,
" immoral, unfailthful, poorly-endowed slimeball.
" Everything's caught on tape.
" Your (soon-to-be-ex) Wife,
" p.s. I paid for this billboard from OUR joint bank account. "
