Making this post because I have seen a few preprints out there similar but this one is the real deal!!! Its staying in my collection forever. Stating this as to why I removed the "George inscription" and posting photos in general but its more for awareness since Dan has changed his style a bit over the years and is now signing a very small shortened signature. Also because there are a few styles of secretarial signatures TTM which are always being confused as authentic

I purchased for $45 hoping it wasn't a preprint with full intention of attempt to remove the name. This can be very tricky on photos signed decades ago because the ink may have become permanently embedded into the gloss, or at best leave a shadow after removal.. regardless, I went ahead knowing this photo should be full gloss 

It arrived today. The ink is very old and hard to differentiate from the photo in the light in person. Even harder on camera, but its is "live ink"

I tested removing a part of the line after George and it removed completely, no shadow. I was thrilled. Kept going and fully removed George... there are extremely faint scratch marks made from the old marker but these can be buffed out carefully although its only visible in light at a certain angle. I may leave as is. 

It may not seem like much of an item to some but to me its priceless. Dan will never sign full this way again. This is a promo photo of him when Ecto 1 was purchased and brought back to the station in the movie. Very happy to add this to my Ghostbusters collection
