The Blue Ernie Banks is just under 14" in length
The Red Ernie Banks is 20" in length
Interestingly, these next two Cubs variations feature similar graphics to the 20" (Red) Ernie Banks. But I believe these are both full-sized 29" pennants. I am 99% sure of it, despite Legendary neglecting to mention the size in their description...
