The frescoes decorating the inside of the House, of which unfortunately only traces remain, show two coat of arms, that can both be linked directly to Mantegna, because they are similar to the one that can be found in the funerary chapel in the Mantua Cathedral of St. Andrew. On the right the sun is visible, the symbol of the Marquise Ludovico, granted to the painter in 1459. On the left a crown surrounded by myrtle, while below we can see two decorated strips on a black background, an echo of the first coat of arms of the Gonzaga family.
