Thank you.
I can't get the search facility to work so didn't realise it had been answered before.
Meant to post this in Quizzes and puzzles, don't know how I ended up in Phrases and sayings.
Yet another blonde moment!
Thanks again

Unless the term 'television advertising' is substituted for 'advertising', this quiz question isn't correct.

I'm sorry...I didn't express my answer clearly. I meant that if the answer is 'Woolworths' then the quiz question isn't correct. Woolworths did use several forms of advertising including handbills.
