Got '57 Monaco grand prix poster 2x3 ft for $160
http://www.allposters.com/-sp/Monaco-Grand-Prix-1957-Posters_i141130_.htm
I am planning on ordering 8-12 more of the 1950s Monaco, Monza, Le Mans races. The artists usually used cool abstract cues to capture the seaside, motorsports, swank feel. Will put 3 more in garage so when you role in Le Mans history is around you.
I (that means my brother) converted by basement (used to be laundry room) off the garage (drywall, pre-fab hard-wood floors, pine-cabinets) into a trophy room and I am going to put 6-8 of these huge prints along one wall as a gallery with leather club chairs, and helmets, plaques, awards in a custom cabinet with a widescreen and a small enclosed bar w/small steel fridge, black granite and panel the corner with wine crate panels. He has been working on it nights/weekends since last Winter! Prince of a guy.
Its all Home-Depot but it looks amazing; esp. when you open the white door to garage and its covered on other side top to bottom with Racing, fuel, parts, tire, watch sponsor stickers.
You know something hot is next door
