I would like to know if there is a common alternative word/expression for the "company stationery", the paper with the company's printed letterhead, in British English.
I am wondering that there are so much words for other things, similar in meaning, but for an essential paper (cover) with printed company logo/head there is only the word "letterhead" which exactly seen, is a part/element of the letter. In Germany we say: Geschäftsbogen, Firmenbogen, often Firmenpapier and Firmenblatt.
Letterhead is the head of the letter, referring to the layout and elements of a letter, but not the whole paper.
