18 Poster Stamps or Cinderellas from Germany.  Includes a set of 12 for the Continental Company, founded in 1871, that produced rubber soles and heels for shoes.  This is Series 84, Numbers 1 through 12.  Only set on Ebay when I looked today.  On the other side of the same piece of light board are six Cinderellas for the Poetzsch Coffee and Tea Company.  Richard Poetzsch (1861-1913) was a major coffee and tea entrepreneur who opened his first shop in 1888.  Before WW I he was one of the market leaders in the industry and employed 120 people.  This lot includes a brief Bio of Poetzsch.  The stamps are numbered 1 through 6.  ALL 18 are glued down.  Bonuses.
