This plaque represents a unique combination of items that is a good reflection on the amazing but too short career of Bo Jackson. First, the large photo depicts his NFL days as a crushing running back for the Raiders. 

Then, the signed baseball card in the upper right corner (certificate of authenticity included) reflects on his playing days in baseball as a member of the Kansas City Royals. 

Finally, below the plaque with his name is a one day cancelled postcard with stamps from the nation of Grenada, honoring three great Kansas City Royals (just not Bo...). The stamps feature Royals stars from the 70s and 80s: George Brett, Dan Quisenberry and Bret Saberhagen.

An odd collection but sure to be a unique addition for the collection of the Royals fan on your list.
