Yes...These pennants are super rare, especially in full size. You're more likely to find the 12" version which the Rams is. And I don't own it. I've never seen it come up for sale. I just found the picture in one of my many internet searches and save it for motivation.
I don't know if I'd buy the mini but would love to find a full size one.
The only full size that I've seen are the Oilers and Steelers.
Some of the minis I've seen...
