The Library of Congress: Performing arts posters and Shakespeare

There is much to explore for the ephemerist in the Library of Congress Prints and Photographs online catalog.
For this series on theatre and entertainment (for Shakespeare week), I will confine this post to the 2114 performing arts posters. These include theatre, magic and minstrels and can be browsed as a list (with thumbnails), a gallery, a grid (as in the screen shot) or as a slide show or searched.  Searching is aided by helpful drop-down lists: a search for opera, for example, prompts opera houses, opera bouffe, opera Normandy, etc as well as operas and operatic.

There are hits for Shakespeare, of course, and additionally the Library of Congress has a special section in its Imagination Gallery (part of American treasures) devoted to Shakespeare in America, which includes ephemera.
