Unregistered

Years ago I came across a painting of a squire dressing a knight and to this day I still can not find any information on it. Any help would be beyond appreciated. Here's what I remember:

The squire is dressing a knight. The knight has reddish/blond ringlets around shoulder length, is rather young, and clean-shaven. I don't think it's a full-body portrait, but I could be mistaken. It has a renaissance era feel to it and the artist may have been Italian.
