This guide will let you know how to unlock the NEW VAMPIRE DRACULA MASK (Dark Green Vintage Vampire Mask) in Grand Theft Auto 5 Online.
You will need to own the CEO’s office and the warehouse. You can buy them from your computer under Special Cargo.
After that, wait for 48 minutes to have enough supplies and then go to the laptop. You have to choose to sell your cargo, then head to the LSI airport and get on a plane. You can do this in an invite-only session. You need to drop your supplies at three different spots to complete the mission and unlock the mask.
After that, go to the Vespucci mask store and navigate to the Vintage Halloween category. You will find the Dark Green Vintage Vampire mask there.
