Budweiser Aladdin's Thermos, Only One of its Kind?

Recently while vintage estate shopping I found this wonderful Budweiser Aladdin's thermos. Even though it was a little pricey for a thermos, I could tell by the Bud logo that it was vintage late 60's-'70's. And since Aladdins is no longer in production, I decided it had double vintage appeal. And WOW how cool is it. I imagined dayworkers longing for a cold Bud while finishing a long days shift. You can imagine how I felt as I tried to play it cool taking my "big score" to the cashier. She asked if I was clear on the price since all my other finds were in the $.50-$1 range. Yeah, I know I said, as I tried to contain myself, "But look how cool it is!"
Later I decided to try and find out more information about the thermos. As cool as this thermos was, I thought it would be rather average in the Budweiser collecting world. My personal collection is standard "rare finds" which means you can get 2 or 3 of them on ebay at any given time. Sure enough plenty of vintage Thermo-Serv Budweiser mugs and a Thermo-Serv thermos with the vintage Bud "Bow-Tie" logo. But what is this.... no Aladdin Thermos' for Budweiser? Nope not one.
So off to the internet we go. Searching and searching and still not one. Not one. Hundreds of Budweiser Collectible sites later... still not one.
It makes me wonder, how long was this thermos in production? Was it made about the time Thermo-Serv took over the Aladdin's production line or long before? Was it part of the only Aladdin-Budweiser production run? How much is it worth? Does the Canadian Budweiser Museum have one? Instead of finding more information about my "cool" Budweiser Label Aladdin Thermos, I only found more questions. And it is these types of vintage mysteries that keep me interested and makes collecting so much fun.
Even the "bow-tie" Thermo-Serv thermos is fairly rare but this Budweiser Label Thermos by Aladdin (oh, did I mention it may be unused and still has the original adverting label on it) seems to be quite unique, in fact it's the only one I can find!?!?! Have Fun & Happy Hunting.
