Zanzibar 1944 1/- Offset Impressions Diagonally in Top Margin

1944 Bicentenary 1/- dull purple (SG 330). VF/UM top left corner block of eight with ADDITIONAL PARTIAL OFFSET IMPRESSIONS DIAGONALLY IN TOP MARGIN. Clearly attributable to the presence of a during-printing paperfold (see scans) causing the margin to fold back onto the still-wet impression. Unusual piece to provide some interest in an otherwise fairly tedious issue!
