What do you do when publishing partners part in middle of a printing? Yalkut Shimoni, Polonnoye, 1805
In 1805, in Polonnoye, a handsome edition of Yalkut Shimoni was published, by the publishers Yosef HaCohen and Shmuel Madpis. In the middle of the printing, after some copies already have been printed, the partnership dissolved and the decision was made to erase the name of the printed Shmuel Madpis from the emblem which appeared on the title page of every copy.
Here is a copy with the original emblem
And here are 2 copies with the words Shmuel Madpis crudely crossed out.
