|Sigismondo and Ercole, the brothers of Leonello, are 9 and 11 years old, so this document refers to a deck for kids.
This is the second entry about Trionfi from Ferrara (same year as the first). After that Trionfi is not mentioned for 8 years in Ferrara in the account books, so one might conclude, that the interest in them is not very high at the beginning. Perhaps they were only interesting to kids, which loved the new figures.
Instead of further early notes about Trionfi decks appear 6 entries, which document an interest in
Imperatori cards (1443). The price is around 12 soldi, which is around 1/8 of the price, which was paid for a single deck for Leonello in February, but, considering, that this is only "for the kids", this doesn't surprize. Still it is a rather expensive toy (a humble worker had
to work a week for this sum) and doesn't allow the conclusion, that a mass market for Trionfi deck existed at this time.
Ercole became later duke of Ferrara and it is assumed, that most of the playing cards that we know from Ferrara are commissioned under his rule.
From Sigismondo is known, that he later lost heavy sums of money in gambling. The merchant Burdochi had in the year 1442 various
exchanges with Sagramoro, the painter of the first mentioned Trionfi cards. From later years nothing is known
about Burdochi, Sagramoro became the favoured Trionfi painter till 1456.
