Both sets I've got are similar in the back designs they show the Main Museum building the first one is in sepia tone the other one in full color.
The Sepia Tone Deck appears to be from the 1960s based on the cars that are shown in the picture. The deck seems to be a promo device for a company called "Superior Dairy Products Build Champions". The box (and the jokers) have some manufacturer information, but not the actual copyright date. It is made by Brown & Bigelow (division of Standard Packaging Corp. St. Paul 4, Minnesota).
Here is the back of the deck box, the Ace of Spades, one of the two identical Jokers and the face cards of the Hearts.
The full color one I used to have a similar one from back when my brother and I visited the Hall around 1980. It is probably made in the late1970s, it could be a more modern issue based on the late 70s version I originally had. Of course that deck is long gone this is a new one. I thought the deck I used to have years ago had the gold flecked edges but I'm not sure if that was true. I might be confusing it with a deck of Disney World cards we had that showed Cinderella's Castle. This one doesn't have the gold on the edge. Anyway this new deck is still sealed I got for $20 delivered. The original "Buy It Now or Best Offer" price was $20.00 with $6.00 shipping. I made an offer of $14 ($20 delivered) and they accepted that. I wasn't going to pay much more than $20 for this set, even with a ton of sentimental value of it. This deck just says "Made in China" not sure of manufacturer. Maybe the Ace of Spades has that info. I won't know unless I find an exact copy that is opened.
