This is a colorful plastic keychain puzzle in the form of a locomotive. These were typically made in the 1960s. In addition to taking it apart and putting it back together, they're desirable for collecting. It measures about 2-1/2 inches long, 1 inch wide, and 1 inch high. Thanks for looking! ****************************************************************** SELLER NOTES: a. P lease examine the photos carefully as an extension of the description.
