Pattern (only in Danish) can also be found for free at Familie Journal - Strik Marys royale svøp.

The original 1950’s pattern was published by Monarch Yarn as cute n’cozy shawl. It may have used a US 8 needle. Gauge is not known (and is not critical unless you want an exact 60” square.)

This is Marianne Knorborg’s translation of the shawl used by Crown Princess Mary of Denmark recently for bringing both of her newborns home from the hospital. The original is a Shetland lace design.

Svøbet er strikket efter en opskrift fra Shetlandsøerne fra 1800-tallet, og i Skotland, hvor Marys forældre stammer fra, bruges disse sjaler stadig både som babysvøb og som sjaler til kvinder i alle aldre.

(In English, that’s 400g thin wool yarn with a ratio of approximately 200m per 50g, but you can knit this up in any yarn - from 1 ply lace to double knit.)

This is a traditional Shetland Hap Shawl, the Danish pattern is likely a translation of an English pattern.
