When I colleceted back in 2001 a Viny Caped Jawa was thought not to exist on a Palitoy 12 Back, now it does, back then people would say they had seen one but no one believed it until they actualy saw one with thier own eyes. Its great that you trust the word of one or two individuals but for me not knowing either of those individuals I need to see it to believe it. I am perfectly happy in not seeing the image as for me it adds an element of intrigue and mystery to collecting which is exiting for me, maybe that's a little odd to some people but that's me.
Darren most certainly has significantly increased the profile of the 41 Back Dengar by not openly showing the pictures, lots of people are talking about it and I am sure the desirability and value of it has increased substantially, its very clever marketing.
The NASA point is relevant in that most people expect to see some kind of visual proof when someone confirms the existence of something new and therefore I do not believe the point is ridiculous. If Darren says today that he also has a 30 Back Dengar does that prove its existence also, where do you stop?
I understand image control but surely you can show people an image without posting it!
