I have been catching up on a lot threads today, and this one is a true standout. Charlie, you should get the APF award for "Thread of the Year."
Your poster energy is off the charts. At least now, you are not staying up all night trying to find Turkish postcards for the Black Swan. The thread is very informative for those who want to learn. And finally, the helpful advice offered to you in the thread shows a great spirit of community.
You have definitely but the final nail in the coffin of me buying any linen posters post 1970. I am amazed at your before and after photos. I might actually devalue a "must have" poster because it has been restored. But, that is only my opinion. I totally understand why a 1945 poster restored would be more enjoyable to look at, but a 1978 Star Wars should be raw.
Your poster baths and crease removal are really looking good.
Keep up the good work,
Brian
