Fantastic pennant, Richie! I've never seen either side, which is somewhat surprising since you might think I would have seen the Aaron in my baseball searches or the Ali in one of the many auction catalogs I've received over the years. I assume the empty square on the Aaron was for a photo.
Didn't Ali fight Foreman more than once? If so, your pennant isn't necessarily Rumble in the Jungle. I love how they decided to do Ali's new name in a middle eastern looking font.
I don't have an idea on value but I would think both Ali and Aaron are highly collected.
