B cards include a large variety of sub-groups, often RP on the trademark Bromide photographic paper.  I take it that many of these were their "novelty" lines.  According to Faulkner, the card numbers run up to 2600, then skip to 5000.  I know of the following types, for which I give limited examples.  Backs are shown elsewhere.  If you have encountered other types of B cards, please scan a sample and send me the file for posting.

        B  Greetings.    A kind of card which must have satisfied someone's taste once.  BW or hand tinted still life real photos on the company's trademark Bromide paper.  Without border but found in both udb and db.  B244 recently sold online in a handtinted version where its pink petals were, I admit, quite attractive.

           B244      Happy Birthday

        B  Animals.  RP cards of posed animals--cats, rabbits, chicks.  The cards are BW, some white-bordered, and bear cute captions.  More later on Harry Rees, the photographic genius who posed all these animals.

           B408          B1410 

        B  Alphabet.  Two series, as far as I know.  One a photographic collage of objects presumably all signified by the same initial.  The letter is a tree, post, or vine-enwrapped shape.  White border, plain back, all bear the NPG logo for a newly-employed photographic process. I am not convinced the second series is  Rotograph at all.  On B 57, the reverse lists "HGZ & Co." as publisher.  But the front carries a Rotograph imprint and a series # in tiny font??  This lithographic card shows a heavy black outline initial with faces of women and girls, as well as flowers, therein. 

            B434          B57   

      B  Large Letter.  RP faces inside large letters of a lithographic design.  The following example, "Martha," is on a smooth, flat photographic paper and has a plain udb.

                 B852    

      B  Dutch Scenes.  These lovely cyan-blue cards feature  children in Dutch costume and playful poses (and possibly other topics on other cards).  There is no border and no NPG imprint (see that listing).  Rather, there is a tiny Rotograph imprint and series number on the front lower right, with the usual plain back.  

              B1016    

       B  Portraits. This group, like the A portrait group, features actors, scenes from plays, presidents, posed scenes, and probably others.  Some cards have no borders, some vertical cards a large white bottom margin, some a white border on all sides.

              B1331        Marguerite Clark

       B  Novelty.  These cards are realphoto with a fantastic edge, in this case depicting the virtue, "Hope."  Some do not bear a 'B' prefix.  See the 'Misc.' page.

                 B2001         "Hope"

       B  Views.  Lest we forget, there are B views--though I have just a few of these, so I'm not sure what to make of the group.  B2497, db, is a BW RP on a very stiff quality paper.  The photo is highly glazed, almost like a modern chrome.   

              B2497        The Flatiron Building, NYC.  The tallest building in the world at the time of its completion in 1902, the 20-storey Flatiron building, located at the intersection of Broadway, 5th Avenue, and 23rd street,  appears on Rotographs frequently enough as to be another company icon.   

        B  Art.  These are not the colorful gallery cards printed by Stengel, but BW photo reproductions of Roman art, very like the A portrait cards.  See also "Le Lion Amoureux" on the puzzles page and try the BExcel file which you can view by following the link above..

             B5032        Gnidian Venus

      B  Ships.  See also the 'C' listing.  Sample below is a rp of the USS Hartford by E. Muller.
