Ltd Booklet, containing two complete panes of ten, with each pane containing two stamps showing the re-entry in left "2" of "25" (CL42f, $375 each stamp). The booklet still has its complete brown cover (folded over in our scan). Only 3 complete booklets are known, and probably very few partial booklets like this one remain.
