March 9, 1929
Preparations are in full swing for the March 21 wedding of Crown Prince Olav and Princess Martha of Sweden. The main area of Oslo is to be framed with "rows of illuminated ice obelisks." The wedding will be broadcast on radio. One labor representative has had to decline his invitations "on orders of a higher authority." A watchmen, entering Oscar's Hall, which has been placed at the engaged couple's disposal, found a bottle that contained about a pound of dynamite. The fuse had not been lit.
Police believe that was placed in the castle by those who are opposed to Oscar's Hall being used as a royal residence.
