To have all, or anywhere near all, the Atlas reefers would require an enormous investment and a very large display space. A friend of mine used to have them all, but he stopped buying several years ago and sold most of the ones he had. It was just too overwhelming to keep up.
I have a pretty substantial collection, but I specialize in beer and wine cars (mostly from Milwaukee or other places on the Milwaukee Road), cars lettered for the Milwaukee Road and its subsidiaries, and the most colorful and interesting of the non-beer cars. I used to buy a lot; now it's half a dozen or so per year. I have no interest in owning them all. I wouldn't have any place to put them.
I would be curious to know which are considered the rarest or most collectible of the Atlas reefers. I'm guessing that the Frank Fehr brewery, Fitger's, and the two Gluek Brewing beer cars are among the hardest to find. And I don't think I've ever seen a Fauerbach beer car for sale on eBay, at a train show, or anywhere else except Dunham's, the dealer that commissioned the car.
There's a website with what may be a complete set of photos of the Atlas billboard reefers. Here's the link: Toy Trains 1 At the bottom of the page he has a link to a PDF of what he says is a complete list.
