Here's another trade card from the 1870's, this one advertising a business in Boston called "J. Baird." They were dealers in "Fancy, Christmas, New Year; and Birthday Cards, Embossed Pictures, chromos, Oleographs, Paper Canoes, Fancy Boxes, Panels, Easels and all fancy Paper Goods."
(New word for me: Oleographs. According to the Getty Art and Architecture Thesaurus, oleographs are chromolithographs printed with oil paint onto a textured surface and often coated with varnish; popular as inexpensive reproductions of oil paintings in the late 19th century.)
Next steps: find out what is at 21 Bedford Street now (possibly the parking garage associated with a Hyatt Hotel); and figure out what "paper canoes" were used for.
