Greg,
First welcome to the boards. Are you concerned that the logo was re-colored or touched up? In most of the examples of the Aaron '55 I have seen has that same imperfection the blue ink "bleeding" onto the yellow background.. Through my exerience collecting the '55 set in high grade it seems like a lot of the yellow background cards will almost always have black spots on them. I do not see anything wrong with your 55. I hope this helps.
