Poster Sample/Dealer Sales Sample • 4"W x 6"H
Note: You can see the code, 6612, which was used by retailers to place their orders from the suppliers/manufacturers.

Instead of lugging large unwieldy posters to buyers, these samples are carried by salespersons so that they can be either mailed to or easily carried & shown to prospective buyers. Somewhere on the these guys (sometimes on the fronts, sometimes the backs) you'll see a series of digits or mixed series of numbers & alphabet letters.
