This is the famous (and #16 in the Top 101 Classic Toy Trains reference book) 1951-52 MARX 934 Mickey Mouse METEOR Train Set in Box and with KEY!  I own some preschools that have had old trains as our foyer decor (The kids loved them!). We had them on shelves high up on the wall along with it's box!  This is one of the 6 Marx Trains from those schools.

This is a litho tin toy and includes the sought after "5th yellow box car" with #1476!  Train is in near perfect condition and engine winds and  works....Box, key and track are  all included.  Box top has one side panel and a portion of another side missing and box bottom is complete with 2 corners seperated!  Will shrink wrap for shipping to keep existing box as it is currently.  Not sure if it sparks or not (we've reduced the price) as it is packed and ready to ship!
