WOW! What a blue kitchen! I am intrigued by the equal-size containers on the shelf behind the children. The containers are numbered 1 through 4. What is interesting about that is that Westinghouse ranges used to have their surface units numbered 1 through 4 in blue porcelain on the white porcelain cooktop and similar numbers beside the surface unit controls. I have not seen too many canister sets with equal sized canisters.

The housewares in the ad are beautiful.What do you suppose those dark blue counters were made of? The illustration is signed by Victor someone whose last name is blocked by the banner. His use of color is amazing. Back when pictures in magazines were painted by illustrators as opposed to being photographs the colors were deeper and more intense which is one of the joys of looking at old magazines.

Two references at the bottom are strictly from the war years.   The time for the program: 2:30 EWT and the mention of the Blue Network. Eastern War Time was a national Daylight Saving Time to help conserve electricity and was in effect from February, 1942 through September, 1945. The Blue Network was an interesting invention of early radio broadcasting when NBC had a Blue, Red and, on the west coast, an Orange Network that usually carried separate programs but could be combined for special events. You can find more information by Googling Blue Network.

I agree that the countertops are most likely linoleum, as that material was highly promoted for such uses. The color selection then was excellent, as evidenced by flooring catalogs of the time.

I see a yellow Hall China covered container on the counter. It looks like those that came with Westinghouse refrigerators & roaster ovens.

Also, unless it was in a basement or other area with the floor sloped to a drain, mopping was likely needed.

For the excellent reasons listed above, that is why the "modern" HE machines that do not use as much water are not as self cleaning when used in poor laundering practices like cold water washing. Modern dishwashers can be the same way with too little water and too few water changes to successfully carry away the food waste.  Both situations have spurred the market for washing machine and dishwasher cleaners.

Great answer, just like GE kitchens used Textolite, their laminate product.
