Anheuser Bush created Malt Nutrine in 1905, and was marketed to help with an assortment of health issues. It was marketed to help with insomnia, was given to new mothers, and was a nerve-quieting tonic.
This tray could have been used in a bar, or even at a soda fountain to deliver the drinks that someone had ordered. The thing to remember about something like this is that since it was in a place like a bar, it would get a lot of wear to both the top and bottom. When a tray gets a ton of wear, the paint starts to flake away to the point where there is nothing left but the metal tray.
So if you happen to find a tray with a ton of the paint left (and not a lot of damage either), it helps retain the value of the piece.
The Malt Nutrine tray can be seen in my Etsy store here.
