This comes from a catalog I have. The cover says "G.&D.Cook & Co's. Illustrated Catalogue of Carriages and Special Business Advertiser New Haven, Ct". The date inside is 1860. Unfortunately, there's no picture of a Landau carriage like the one in xenon_zircon_23's earlier post - they may have been too sophisticated for the New Haven market that early. More about landaus here.
There are some great ads in this catalog - I'll try and post more as soon as I get my scanner running again, if anyone's interested.
