A lot of persons with blonde hairs ... considering the board size, they're likely occupied in a game of Rithmomachia.
The association of the Cassone picture of Scheggia with the Alessandro Sforza Temperance card came up with the observation of the way, how the painter handled the breasts in both cases (in combination with the blonde hair). And from the condition, that Scheggia made indeed playing cards in 1447 and that he was related to the Medici (birth tray of Lorenzo in 1449). And a little bit, cause the brother Masaccio made the Adam-Eve motif in a manner, that reminds the Tower scene in Minchiate.
Blonde hairs alone ...
... make not enough to be related.
There was a fashion with blonde hairs. The ladies made complicated operations to get it done.
Something else ... there were two courts cards with great similarities to the Fante of the Charles VI Tarot, which had appeared as a new finding some years ago. As far I remember, there was also an IPCS article ... we had the pictures. But I don't know, where these pictures are.
Actually these pictures should be part of our discussions, and also this article. Does somebody remember?
... some moments later ... :-)
I found them. Thierry Depaulis, Two fifteenth-century Italian cards, IPCS vol 38, 4, p. 264-270.
I remember, that the web had also other pictures, where they didn't look so yellow, I remember more grey.
The Fante of Swords is clearly similar to the Charles VI Fante of Swords, but it's not the same. The size is considerable smaller, Depaulis gives 135/139 x 70/74 mm against 180/185 x 90/95 mm for the Charles VI. The Charles VI has a hidden paper wrapped around the border of the cards, which these smaller and cheaper cards have not.
