The seal represents an imperial dragon in red porfido stone. On the lateral of the base, it seems that is written "Year of the dragon, Hu Zhengyan", the 1584-1674, printer, artist and seals carver.
- On the base of the seal is in the "Small Seal Script", imperial red background. That I do not know how to decipher. It should be the name of the nobleman to whom the seal was carved for signature.
I would like to know what it says.
Many thanks in advance Aurelio
