Human Factors
I tore the Crew listing off the blank ATIS sheets to put on the Captain's side by the HGS dim control knob. The HGS was MEL'ed and had a stricter under the dim control knob. I didn't want to cover up the sticker; so I elected to try and put the Crew listing on the ledge above the lower DU. When I tried to balance it there; it slipped behind the lower DU. I should have stopped what I was doing right then; told the Captain; and called Maintenance. Instead; I elected to do my walkaround and inform everyone after; in case I found something else on the walkaround. I completed my walkaround uneventfully and got sidetracked with conversation with the Gate Attendant; Flight Attendants; and Captain as I completed my preflight duties and completely forgot about the Crew listing slipping behind the lower DU. After completing the flights for the day and getting to the hotel; I remembered I didn't report the incident. I called my Chief Pilot and the on call Chief Pilot to report it. I talked to the Maintenance Rep and told him the story too. The Maintenance Rep told me the aircraft was due to land in ZZZ and they would check it out; but felt it was not a going to be a problem.
First Officer reported that distraction caused him to forget to inform the Captain and Maintenance about an issue.
