Smoking and Other Hobbies
This mission can be started in Flatneck station, south from the gang hideout in Horseshoe Overlook (the same location where you can find Reverend Swanson during one of the main missions.)
Meet with Phineas T. Ramsbottom. The man is interested in collecting Cigarette cards. You can sell him cards whenever you collect a full set. You can send him your collection by visiting a post office.
Note: Don’t sell single cards to traders!
