Icy-Hot pic-nic box

I picked up this Icy-Hot pic-nic box at an auction and cannot find it on the internet. There are two layers in the main part of the box. The top row contains a thermos-like container with very wide mouth and a cork stopper, and a metal box with clasp that appears to be for food. The second layer contains two glass lined thermos-like containers with corks. Plates are labelled Sweden and all utensils are marked Icy Hot. I see Icy Hot was acquired by Thermos in the 20's, but I am not finding any old Icy Hot catalogs, etc. Is this real, or did someone piece together a kit using Icy-Hot items? Did the Icy-Hot brand disappear when Thermos acquired them in the 20's? Is this a common item?
