After getting dozens of crushed/destroyed posters, I finally got motivated to post a basic primer on shipping posters on MoviePosterCollectors.com at this address:
http://www.moviepostercollectors.com/Shipping_Posters.html
I recommend adding this link to your "Favorites" list and sending it to unknown shippers to prevent poster tragedies.
Since it is aimed at novice shippers on Ebay, kept it pretty basic. Most novice shippers are not going to "sleeve" a poster, so I left that out. (And really I don't agree with sleeving posters anyway because the poster usually ends up rolled too tight).
Any constructive suggestions welcome, but it took me a year to get motivate to put it together, so it may take a year to make any additional changes
