OK first of all if someone showed a stash of gold 2x4 bricks or had a couple dozen Mr. Gold you could beat this image... but this is the most valuable piece of LEGO small scale real estate I have ever seen in my 54 years of collecting!
This scene (plus the boxes that the parts came in)... would fetch (at auction) over $18,000 USD, or 16.000 Euros or GBP 12,000... :o
Most of the items here are in a category of "fewer than 10 known"....
The Norwegian owner of this diorama sent me this image this morning... and I'm still in a state of shock...
I'll give out one quick hint... the yellow auto is a 1957 prototype... produced by A/S Norske LEGIO (yes there's an "I" in this name).... the Norwegian licensee for LEGO from 1953-62 while a toy import ban was in place. That auto is a Opel Kapitän, one of only 3 known in yellow (8 others are known in other colors)... and this auto is worth about GBP 4,000+ (over $5,000).
This image will be the new cover to my Unofficial LEGO Sets/Parts Collectors Guide chapter cover page on LEGO Garages & Service Stations.
Box images and details to follow shortly! :p
