As promised here is a look at my Ghostbusters display. Full disclosure, this display has been ripped down and put in the collection room in a much smaller form. This was up for the new movie (I did the same thing for Star Wars last year).
Let's take a look at how the display looked in it's entirety.
Unfortunately I didn't think to take closer images of the stuff on the wall, but all of it but the stuff I did focus in on are just printed on a computer.
ECTO-FRIGGIN COOLER! I remember this as a kid and was so excited that it was coming back ECTO-COOLER! Also in the picture are "paper crafts of old ecto-cooler packages that I found online and printed!
