Help naming an old KEM deck

[Chuqii]

Picked this deck up on Ebay recently, but I can't track down the name of this type of back.  Ace date code is C140.  Anyone know it?

Update - deck name is Stratosphere

Thanks for the help.

Beats me.  If I remember the dating convention correctly for Kem decks, this one was manufactured January 1940.  It looks to be about the right artistic style for that period.  It's not a name, but it's a place to start.  I think this deck also predates the use of an extra card for ordering replacements for broken cards, meaning it'll be a little tougher to find that title.

You are correct on the dating of the deck to Jan 1940.  I was able to find an old newspaper ad from December 1939 showing the deck, but no luck on the name.  And I don't know the names of the other two decks shown in the ad, either.  But I'd love to have them if anyone has one for sale.
