The addition of a 1d green value to a commemorative series reflects the large volumes of military concessional mail. Far from being a frivolous issue, it was a well thought out propaganda series. Even the 6d reflected the serious wartime conditions of usefulness. Ordinarily the high value of a commemorative was a little used but lucrative denomination of 1/- or above.
The 3d has a interesting variety of a ship in the side margin of sheets.
