My apologies if this has been discussed already (I could not find it in my search).
I recently bought a poster in an on-line auction that was pre-1985. Little did I know that I would not be able to trot down to Michael's or the like to get a frame because standard poster frames now (and since 1985) are 27 x 40 as opposed to 27 x 41 pre-1985. My question is why did the industry change to add 1 inch to the dimensions? I would imagine this was not an easy change equipment wise, etc.
Thanks,
Matthew
