For several years Norwegian booksellers and collectors have been aware of the fact that there are some first editions of three of Henrik Ibsen's playsrr Qther than those ordinary first editions published in Copenhagen. According to Schiøtz &. Ringstr@ms book "Norske Fprsteutgaver" U990], these copies have never been recorded sold or owned in Norway' . The University Llbrary in Oslo owns all three of them and lists them in their catalogue: "Henrik Ibsen - Katalog over Ibsenutstillingen i Universitetsbiblioteket, 1928".' Ibsen's books and the different editions have been thoroughly investigated, but this little mystery seemed never to have caught any serious attention.
