No display base is OK I guess, as well as no display case.... Moebius advised us ages ago that there wouldn't be any of these. I had a glass display case built especially for mine with anodized silver finish aluminum framing. Still waiting for the Jupiter though. Inside the display case I am using an alien landscape poster on the background panel. For the "ground" or base of the display case I am keeping it simple... plain matt black "tarmac" with an 18inch diameter yellow circle, similar to the landing pad in the Lost in Space episode 'The Ghost Planet'. :love
Also... a website has been around for at least 18months taking preorders on pretty cool display cases for 18inch Jupiter 2s or other models to display... but I am not sure what is happening with them....whether they are actually going into production of these display cases (??) I was going to get one of them, but I decided to have one built to my specs locally. Here is their link anyway.... Genesis Display Cabinets - Cabinet Customizations
Did you paint the circle for your landing pad or did you get a decal?
I don't think I could mask 2 perfect circles and paint them, so I'm
looking at a vinyl decal as an alternative.
