Type 1: The loop of the "9" of "1920" is large, the tail is small and tapers to a point below the center of the figure.

Type 2: The loop of the "9" is small, the tail is not tapered and extends the full width of the figure. This type was produced by two methods:

    Plate A, lithographed, sheet about 203×253mm, block 39×49mm

    Plate B, offset printed, sheet about 205×252mm, block 39¼×49mm

It is difficult to measure the small difference in blocks.

Identifying the Plates of Type 2 by Flaws

 Variations of ink and shade are not dependable. The following flaws will help in identification:

Plate A: seals #7, 17, 27, 40, 57, 67, 77, and 90 show a larger than normal dent in Santa's cuff to the right of the boy's elbow. On #23, and 73 Santa's right eye is almost missing. On #36, and 86 there is a blue dot on the boy's shoulder above Santa's hand.

Plate B: #34, 35, 84, and 85 the left end of the lower arm of the cross is rounded. On #35, and 85 there is a spur on the first wrinkle of Santa's left coat sleeve, near the right side.
