It's an apothecary shop at the moment, but in a few decades this building will be home to Ticknor and Fields, the leading American publisher of their day. That might sound a bit dull, but this building will be at the centre of American literature and thinking. Authors like Henry Wadsworth Longfellow, Nathaniel Hawthorne Harriet Breecher Stowe, even Charles Dickers will all meet here.
Of course, given the state of American education, it's possible you don't know who any of those people are. I could have said Minty Clitheroe and Pippy BoomBoom and you'd still have looked impressed.
