Rockstar will offer a free GTA 6 cover poster and Leonida map download at launch

This comes from Rockstar Games itself, or from a source passing on its official announcement, so nothing here is a guess. See the source
Rockstar Games has detailed a small set of launch extras for Grand Theft Auto VI. A printable poster of the cover art and a map of Leonida will both be offered as free digital downloads on the game's official website on November 19, launch day.
A physical, double-sized version of the poster is planned for the Rockstar Store "shortly after launch" at 99 cents, or free with any other Rockstar Store purchase. Based on the details shared, the map itself is a digital download; Rockstar has not announced a printed map for sale.
The extras recall the fold-out posters and maps that used to ship in boxed GTA releases. GTA 6 is digital only, so retail boxes contain a download code rather than a disc, and Rockstar has not said whether anything else will be included inside. Separately, Walmart orders have been reported to come with an unspecified surprise.
