The complete set of c.1878 H804-6 Forbes Co. trade cards featured six whimsical images of illustrated ballplayers in baseball poses. The different cards included in the set were "A Fly", "Foul", "Home Run", "Judgment", "Muff", and "Twist". Cards often featured advertising for businesses applied to either the front or back.

Though the tag in the SGC holder labels this example as "A Fly," presented here is the issue titled "Foul" with an advertisement for George F. Ropes Co. on the front. Bright colors and the beautifully period appropriate uniforms give this card tremendous eye appeal.

SGC has only ever graded 33 total examples of this "Foul" postcard with all of the ten different known variations of its advertisements combined.
