This is a very rare puzzle by the very rare Japanese brand Bigben. The title is On Route 66, by Ron Crabb, and it is one of his oil on canvas paintings.
The puzzle had the factory seal originally. However, it was opened in order to remove the puzzle glue due to shipping restrictions. For that reason, it is listed as like NEW, with its original SEALED BAG. The box is in excellent, like new, condition.
It measures 73 x 102 cm. The reference number is 20-12.
