Alerts RS to the fact that there is an 'underhand sale' of the prints of [H. W.] Pickersgill's portrait of JH going on, as JH's cousin bought one.

Assures JH that engravers typically take for themselves a few copies of any print they have made. If a large number of these appear for sale, then it is fraud. Suggests JH not act because the engraver is 'insane' and the exposure would hurt his family.
