Overall Picture (Type I)
Overall Picture (Type II)
There are numerous minor differences in the figures in the lithograph (size, way they face, etc.) but the upper left panel is the fastest and most accurate way to distinguish between the two types. The Type II picture has a darker overall appearance with more black. Thus far, the Type II has been recorded on thicker stock paper (9mm) than the Type I (8mm).
