Each of Fallout: New Vegas’s main story DLCs has a collectible snow globe the player can pick up and add to their collection. In the case of the Honest Hearts DLC, the snow globe can be found in the Zion General Store in Zion Valley.

Quick tips before you set off to get the snow globe:

• Honest Hearts DLC required. To get this snow globe, you need to have the Honest Hearts DLC installed. 
• Added to collection instantly. Unlike the snow globes from the base games, the DLC snow globes are added to your collection at the Lucky 38 instantly. This also means that you are immediately granted the 2000 cap reward for finding it.

Acquisition

To acquire this snow globe, you’ll have to make your way to the Zion General Store, located west of the Zion Fishing Lodge.

Once there, look for a door to enter the general store and go inside. 

Once inside, you’ll see a cash register on the right side of the room. Get behind it.

You’ll see a shelf standing against the wall. The snow globe is on the bottom of that shelf.
