I got this bug to start mapping the locations of the Victorian era portrait studios whose cartes-de-visite and cased images I had collected. I think what got me interested was noticing the proximity of Mathew Brady's studio to one of his New York competitors. I've compiled a very short list of the ones I've been able to get addresses for between my own collection and casual ebay searches. Any assistance in filling in this list you all can provide would be much appreciated. I've got the Google Map of it posted on my blog for anyone who wants to see it. My goal is to keep doing this for New York, and fill in Washington DC and Philadelphia as well when I can get more data. STUDIO NAME ADDRESS DATES OF OPERATION R.A.
