Spalding baseball in box - help with date

[Huysmans]

A hint to the ball's intended audience is probably the Spanish text on the box, with the ball likely produced originally for use in Mexico.

It most closely resembles the box that Spalding used for their ONL baseballs from 1947 to 1957, although those have the text "THE ADOPTED BALL OF THE NATIONAL LEAGUE" where yours has "FAMOUS THROUGHOUT THE WORLD." I would side with Brent on this one that your ball was produced for use in Mexico or South America in that timeframe, though what specific league or other specification the "SC" may be referring to, I do not know. I have previously had a similar situation with sealed balls in which the box was very very similar to the Official National League, which I surmised had to do with them being specifically for use in Canada (see images below).

Most of the various minor league balls produced over the years tend to have very similar if not identical packaging to the manufacturer's ONL or OAL counterparts, which can be useful for narrowing down the timeframe for their manufacture and use. There are likely more tell-tale signs on the ball itself, which I would be curious to see, but I can understand you not wanting to break the seal.

Thanks again for the info guys! Makes sense. If the ball was yours would you open it?

As I said before I dont collect baseballs but I am under self quarantine like most of tri state area and have plenty of time to google search and came up with 2 similar boxes. Both of them have the same text on the patent registration panel. it could be that all 3 were made for use in Mexico. But then why only one panel in spanish.
As you can see one box is for a Frick National leauge ball. I would think that is the packaging used for all National league balls in that timeframe.
But still left with mystery of what is an SC ball?
