We get so many calls and inquiries about A0 picture, or poster, frames that we thought it it only fair to elucidate on the subject matter for the benefit  of Customers, visitors and readers.   An approach as good as any to  explain this subject might be:  'Who, What, Where, When and Why',  to wit,  the 'Five Ws' mnemonic verse which assists writers in fully and properly detailing,  describing or explaining an event, happening. or story.  Incidentally, the Five Ws aren't a modern invention.  It would seem that it was  an ancient Greek rhetorician, Hermagoras of Temnos, of around about 2,000 years ago who invented this popular aide-memoire.
