Mexican Pepsi Atlas 18

I always liked foreign marked American made coolers. This one probably surfaced at Chicago. I am restablishing my cooler collection after a 15 year hiatus. Pulling them out of storage one by one. I had two atlas 18 Dr Peppers. (Sorry just sold the extra one) I am looking for an Atlas 18 in Seven Up and Dads Root Beer.
I collected all of these in the 90's. It seems that the coolers that we couldn't find then are around now (Double Cola Atlas 18's were considered Rare) and some of these that were easy to spot are mostly in collections now.
