The one on the right, within the original post's image, has received so much attention, and as it turns out, for good reason, for that's the "cookie", the one of 1913...




The maroon of 1913 is brighter, richer...

The yellow-green of 1913 is too....

But then, these are used.
Yes, the "diamonds" at the corners of each do differ somewhat, and the maroon portion of the design does shift over towards the left, of 1924; no surprise there. The same of 1913 shifts, too, to the left as well, although not as drastically. Yes, the dies do differ...

Flat-plate, "Gutenberg" printings are the best.
I would not go out of my way to purchase either one, unless I wanted to assemble either set. I can't recall from where these two came. They may have been my father's, or I got them in the city in the 1990s, or from a combination of both sources. I may just try to assemble the set of 1913, as I do prefer first printings, and throughout my collection.
In the end, the one of 1924 is the doppelgänger, the "evil twin".
