On page 374, Marler states: "In 19 Subjects of Plates 1 and 2 there is in the white band around the portrait oval, either below E or at right center, either a single line or a group of lines. Whether this is a consequence of a re-entry or not, the author cannot say, but he considers them not to be of sufficient importance to warrant describing them, particularly as many of them are much the same in their general appearance."
In an article to be published in a future issue of "The Admiral's Log", Leopold Beaudet and I suggest that these "Notch" varieties are actually quite interesting. We have found over 40 different instances and many plate positions have been determined using the plate proofs at Library and Archives Canada.
A search using "Notch" in the Tag List search field will show the positions which have been plated. A series of tags has been added to help with identification. For more help plating these "Notch" varieties - visit this page.
