~~~ might have been designed as a 3-letter monogram where the larger, central letter is the initial of the last name and the first name initial to the left and the middle name initial to the right..?

So, maybe the graphic isn't "...Espy" as suggested but, rather the monogram of EYSP; first name E, middle name Y and last name SP... with the configuration ESPY, such as Elina Yolanda de Sāo Paulo... maybe ?

What ever it is, the choice of the X-mold was a good one for the 400-piece set.
