Here's a lovely advertising insert from a vintage Pelikan typewriter ribbon. (Thanks to Bill M for the tip on it!) What a luscious product: a bakelite round box with a golden top that unscrews, embossed with the Pelikan logo; a metal Olivetti spool wrapped in foil, again with the logo; a clever uninked end of the silk ribbon; and best of all, this fanfold advertising. Unwrapping this ribbon was like unwrapping gourmet chocolate. I would guess that this dates from the early '60s; how about you?
