Show Some Culture, Jack starts with Tammy Tumbler during Gumshoe in the Opera. The actual objective happens much later in the mission: after the opera singer boss, look for the photo marker between the box seats in the burning opera house to secure the 100 Coins reward.

How to start Show Some Culture, Jack
Start Gumshoe in the Opera walkthrough, then return to the hub before you push too far into the mission flow. Tammy Tumbler stands near the Ammo Shop and gives you the side job.
Accept it before you finish the mission. It is one of the earliest missable side jobs in the game.
Walkthrough
- Accept the job from Tammy in the hub.
- Play through Gumshoe in the Opera normally until you beat the opera singer boss.
- During the fire escape sequence, keep climbing until you reach the walkway between the box seats.
- Watch for the investigation marker over the celebrity seating area.
- Interact with it to take the required photo.
The joke is that the opera house is already in chaos by the time you get the shot, but the marker in the box-seat section is still the correct finish trigger.
Rewards
After you clear the mission and return to Tammy, she gives you 100 Coins.
This is not a huge reward compared with later schematic jobs, but it is one of the safest early completionist pickups because it fits directly into the main mission route.
FAQ
Can you finish Show Some Culture, Jack before the boss fight?
No. The photo point only appears after the opera singer fight once the building starts burning.
Where is Tammy when the job unlocks?
She is in the hub near the Ammo Shop and the P.I. Office.
