Yes, there is a lot of heraldic. And this other heraldic might be the heraldic from "somebody else".
But the crowned dolphin is "only heraldic" ... nothing else. And there is a parallel to the twice appearing Visconti viper in the Sforza decks ... also "only heraldic". From this it is plausible, that this card indicates the "owner".
The dauphin of spring 1461 sits in Genappe, Belgium, then Burgundy - in exile. He was escaped the attack of his father in 1456 and took refuge there.
He loved especially the hunting possibilities of the region - Burgundy was famous for its falcons (see falconer).
The European crowns send their diplomats to his court, as it was expected, that soon Dauphin Louis - though still powerless - would become the powerful king of France and a new time would start.
Everybody, who took the opportunity to be friendly then to the "humble" Louis, would have the chance, that Louis would remember his favor when Louis would become king of France.
His young Savoy wife just had gotten a son (?), who survived ... for the moment (other births before went bad, a son and daughter had died).

Spring 1461: A Milanese painter got the order to learn from Rogier van Weyden in Brussels. Roger agreed.
But the painter was invited to do some work for Louis. Rogier van Weyden was disgusted, as it wasn't his interest, that "foreign painters" got commissions, which otherwise would have gone to Flemish artists. And the painter consumed too much vine. Bianca Maria Visconti, duchessa of Milan, had to write humble letters, that the painter could stay a pupil of Roger.
It's not known, what sort of commission the Milanese painter fulfilled for Louis. It's somehow natural, that he worked at a "Milanese special art" ... something, which wasn't offered in Burgundian countries.

Goldschmidt cards: Queen with castle
... observe the chequered ground, as it appears variously in the Goldschmidt cards (
chess). Observe the accompanying lady-in-waiting, typical in the
chess-influenced Cary-Yale Tarocchi (Empress and Emperor)and early
chess queen figures.
How the cards possibly came to Sevilla ...
Henry [French king 1547 - 1459, * 1519] was born in the royal Château de Saint-Germain-en-Laye, near Paris, the son of Francis I and Claude, Duchess of Brittany (daughter of Louis XII of France and Anne, Duchess of Brittany).
His father was captured at the Battle of Pavia in 1525 by his sworn enemy, Charles V, Holy Roman Emperor, and held prisoner in Spain. To obtain his release it was eventually agreed that Henry and his older brother be sent to Spain in his place. They remained in captivity for three years.
It's plausible, that young princes in captivity had "some toys from home". Naturally this would be "worthwhile toys".
Dummett declares, that ""Vim vi" is a motto used by various Italian families, and he says: "but I've not been able to discover one for whom playing cards are likely to have been painted". Dummett gives the information, that "the Guildhall catalogue records both pairs as having been found in an old chest in Seville" (Spain).

It's difficult to get information, where the boys had been during their captivity. (? ... perhaps you can solve this problem ?)
I remember dark, that we had confirmation, that they at least for some time they were also at Sevilla. At least this period is called the "golden age of Sevilla" (from 1492 till end of 16th century), so the city was great importance then cause the detection of America and a port with privilege to receive incoming ships nearby.
The "captivity of princes" usually was used to influence future rulers positively, so that they would think not too bad of their hosts ... one cannot assume, that the boys had a bad stay in Spain.
