![Salesman's Sample #706](http://www.collectingkeystone.com/wp-content/uploads/2024/02/Salesmans-Sample-706-1024x879.jpg)
This is a unique piece. It is a salesman’s sample but it is early enough that the box is plain and devoid of any logo. The only thing that denotes it as a Keystone toy is the sample tag. The set appears in the 1950 catalog but maybe earlier .
From my private collection.
