Not sure what you mean by "vintage". You cannot judge the date of the autograph by the style/era of the image. He might have signed a still from Marnie the day before he passed away - that would not be a "vintage" autograph.
This is a bad fake. Unfortunately, his autograph looks easy to replicate so all the usual suspects have had a go, and continue to do so.
For future reference, his greetings, such as "Best Wishes" are usually a little illegible at times - so be suspicious of anything which appears clear and neatly drawn.
