1901 composite essay sheetlet for all six duties. Only the 4d design was adopted as a base for all the issued duties. Printed in deep blue on thin gummed wove paper. Signed 'J Heijstek' and datestamped '6 JANUARI 1901.' Also showing previously unrecorded (?) variety "lower right corner '6' omitted" on the 6d essay. Odd edge fault. Very rare, with less than nine sheets believed to exist, some undated.
