I have the map from the fancy Legends & Lore set.
The westernmost thing on it is the isle of Tuern, way out in the Trackless Sea.
Across the northern border are (west to east) Sea of Moving Ice, Reghed Glacier, The High Ice, The Great Glacier, and Peluvia.
Across the eastern border are (north to south) Narfell, Thay, Mulhorand, and The Eastern Shaar.
Across the southern border (west to east): Trackless Sea, Chult (depicted as a peninsula), Serpentes, Halruaa
Pretty much all of the 5E Forgotten Realms adventure sites are located on the map, and locations for the previously non-FR adventures reprinted in Tales from the Yawning Portal and Ghosts of Saltmarsh are also indicated (for example, the Tomb of Horrors is on the eastern border of The High Moor, and Saltmarsh is in Sembia on the Sea of Fallen Stars).
There are also insert bubbles at the four corners depicting Eberron, Krynn, The Radiant Citadel, Spelljammer, and Feywild/Shadowfell.
It's a VERY fun map as a commermorative 5E art piece. It certainly depicts more of FR than any previously published 5E map.
The book, however, is a total hagiography. A coffee table puff-piece commercial which explains why each 5E publication is probably the greatest thing ever and you can't pick your favorite because they are all your favorite. Nothing bad has happened at all since 2013.
