RSVP card

The RSVP card is a paper note in the Fallout 76 update Wastelanders.

Background
This card is used as a clue during the quest Trade Secrets, with the date of March 4, 2048, being a possible clue to the password needed to access the safe room. 030448 is ultimately the correct code, though this note also reveals that Daniel Hornwright did not attend his own daughter's 29th birthday.

Location
The note is on a bar countertop in Hornwright Estate.
