I have 2 with similar borders, one he is pictured with his dad. I also have 5 others that have a "rainbow" type border of purple, green pink blue mixes with the same back. Then I have five gold border cards of Griffey Jr. but the stats include the 1990 stats and the back is a blue shade. Then another one with similar border as yours but with the 1990 stat line as well. And a green border one as well.
All this to say that Griffey Jr. was a very popular subject in the early 1990s for unlicensed card manufacturers.
