Bruce is right about such massive items
I have some Coca-Cola paintings that are recreations of classic Coke ads from the 20s-30s that were done for a restaurant some 40 years ago. They are large, and I have displayed them at different times, but only where I could due to space.
for instance, I have a recreation of the great Haddon Sudbloom ad featuring Charlie McCarthy and the Coke Sprite (originally doen by Sundbloom in 1949). Sundbloom's piece would be better - if it exists (Sundbloom art is a long story), it probably isn't any bigger than 12-18 inches tall. This piece is 12 foot tall, and as you can suspect, it hasn't been displayed much.
Then I have another that repros an ad from 1923 - "6,000,000 sold each day"
this one is only 4 feet tall.. but it's 12 feet wide!!
right now the canvasses are rolled up in a tube 20 feet from where I'm sitting
