These are a booklet pane of 6 (without the tab) and a partial booklet pane (499e in Scott catalog).

I am no expert but to my eye the stamps appear trimmed on the right side, I could be wrong or maybe that's just how they were cut back then?

The booklet pane without tab was just cut high and left, the partial pane was cut left. Not uncommon, the constant fight with paper shrinkage at the time.

Thank y'all for the info. I've listed them as 499(e) in my inventory and I'm so glad to have that mystery solved.

I don't want to press my luck, but can anyone help me understand what distinguishes these stamps as 499(e), as opposed to one of the four zillion other 2-cent red/carmine George Washington stamps? It's been a while since I pored over Scott's trying to narrow things down, but I puzzled over these on my own for a long time and kind of want to know what I should have been looking at/for.

The imperforate edges on 2 or 3 sides made the blocks easily identifiable as coming from a booklet pane. In case you are not familiar with stamp booklets, here are some pictures from the internet.




Since you said they were Perf 11, that narrowed it down to 499e. There are a number of other Perf 11 2-cent Washingtons, but none of the other Perf 11's were issued in booklet form, only as sheets of 100.

The Scott Specialized catalog has a good section of information about how booklet panes were printed, including the plate layout for the 360-stamp sheets that were printed of this issue before cutting them down into booklet panes of 6.
