Typical plate 4 hairlines and retouching of the top two lines in the upper right.

Research notes:

While not discussed in his book, Marler's personal collection had additional CPVs, usually with multiple examples.

  • Right end of the top two horizontal lines strengthened.

  • 4UL34, 4UL51, and 4UL55 all have two lines strengthened.
