1978 JNF Children's Forest issue spectacular error pane (4x2): rather than Hebrew-language stamp of children planting tree alternate with bi-lingual title stamp on each row, here a) two of one followed by alternating designs after, b) missing perforations: middle horizontal + 1st vertical perforation from left, and c) color-misprint on all the stamps, creating a shadow-effect on the texts and some image devices. Not gummed, mint/unused. Undocumented in Rochlin; based on A412-413.
