A useful marketing tool used by Topps from 1952 to 1957, Salesman Samples were mailed and hand distributed to their vast network of jobbers (wholesalers), direct markets - large and small - and consolidators, all of whom would receive these small panels in advance of a new release.  Primarily associated with their Baseball cards, Topps would include some ad copy on the reverse usually paired with a sample back from the issue being repped.  Salesman Samples are prized today for their scarcity, visual appeal and oddball character. 

This 1962 panel is a perfect example of how these were composed, from the trio of players on the front to the colorful ad on the reverse and sterling use of the new single season home run leader's 1961 stats, the second year in a row Maris was used like this.  The condition is roughly Good, with a vertical crease and rounded corners seen, with a small scuff on the Savage card also present.  The reverse is colorful, although a little out of register as seen on the stamps. These early 60's panels are tough items and they do not come up for sale or auction often.
