I'm sure they look nice, but Advance Character posters with company and website info? Heavy duty plastic laminate? These lead me to believe that they were not meant for 'in-house' use. At least, not initially. Heavy plastic laminate is usually used for posters that will be exposed to the elements (Outdoor). High-gloss is usually meant to impress. Unless, they were for some trade show or large event (where one-offs would have more likely been used), something just doesn't sound right with the info....
Recently, Focus Features used ink printed onto thin 100% plastic 'paper' for review one-sheets for The American and Jane Eyre, but this may have been because of an extreme amount of very small text.
Also, Bruce's Aladdin Genie teaser is a wilding poster... so are the Fight Club teasers... and I'm pretty sure the Gattaca is a wilding... really Bruce? It's a good thing that you have 50+ people 'correcting' your 'expertise'. How much do you pay for their service?
Posting Mark's unsupported comment verbatim on the auction listing is something DaveMasterpieces would do... a cheap (cheaper than usual) sale tactic...
