“I would like to thank ATG readers who have commented on our discussion about Portrait of a Young Boy, Perhaps a Prince, or on other topics on our website.
“Further helpful and interesting comments about the possible identity of this sitter have appeared in recent weeks. It is particularly exciting that another version of this fascinating portrait has emerged, in a private collection and in the details close to the one at Alfred East Gallery.
“More information is sure to emerge, perhaps even more versions, and we should probably look within European collections too.”
