<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">printed stationery</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for letterhead that I've seen before include "Address, name etc printed at top of notepaper" , "Printed address on stationery" , "Heading on stationery" , "Where name and address are shown" , "Preprinted name, address etc at top of notepaper" .)
