The cover is nicely done, and the unusual feature of the double spread and having the index numbers on each car with the key table on the inside of the back cover... it makes a very attractive and informative feature.
The "modern Marx" is great stuff, the Flynns did a beautiful job with design, it is truly classic tinplate. I have allowed myself a couple accessories (they did a Green Mtn/Rutland Railroad bridge!!) but thus far have otherwise kept my Marx to prewar. That may have to change...
