Old Vertical Orange Crush Sign

Just bought this old vertical Orange Crush sign. Measures 53" high by 17 1/4" wide. Have not seen a similar sign on-line searching around. Crushy is on the bottle label. The bottle is ribbed.
Hoping someone can help identify this sign and roughly from what year it was made. The markings are not identifyable.
Would appreciate thoughts on approach to clean this up and bring back some of the colors.....based on the fading, think it has spent many years exposed to the elements nailed to a building.

Thanks for any help!
