Just added two more cartes-de-visite to the collection, both Mathew Bradys. My first Brady celebrity card – General Joseph Hooker, and my first Brady from his Washington studio. The DC studio mark seems far more rare than the New York studio, so far. Maybe I’m just not looking in the right places for them, but out of the seven I have, only one is the DC studio, and of the ones I’ve looked at, maybe 50 or so, I think I’ve only seen the DC imprint two or three times.
