laughing boy terracotta

terracotta bust made c.1498, probably by guido mazzoni, believed to be a young henry VIII. stylistically akin to mazzoni's work, its date is a guess based on the belief that this is indeed henry aged 7. guido died in 1518, and was in paris working on the french king's tomb in the 1490s, putting in a bid on doing henry VII's tomb at that time. however, henry's older brother arthur tudor would have been 7 in 1493, so even if its provenance and the richness of the clothing imply a royal english prince, could it not have been either henry or arthur ?
