Galdrakver (Lbs 2917 a 4to) — a quarto galdrabók written by Olgeir Geirsson in Akureyri in 1868–1869, bound in leather and devoted in roughly equal measure to chiromancy and galdrastafir.

Twenty-seven named staves are set out in sequence with their captions and instructions, with the vegvísir given as symbol number 27 on page 27, accompanied by an inscription partly in Latin and partly in runes — the second-earliest known attestation of the vegvísir after Huld.

The manuscript also carries fishing staves and other working signs from the late Icelandic magical tradition.

Catalogued in the Lbs collection at the Landsbókasafn Íslands–Háskólabókasafn in Reykjavík.
