Stamps of Israel are printed in sheets with tabs (labels) usually attached below the bottom row. The tabs contain a statement or pictorial elaboration about the stamp’s subject. The Israel Philatelic Services also prepares an official envelope for use on the first day of a stamp’s issue, which when postmarked with the new stamp affixed is referred to as a First Day Cover. The envelope usually contains an illustration pertaining to the stamp’s theme.
