I dug a bit more to find the origin of the photo and found that it's from a collection taken by Harry Burton. The series about Tutankhamun's Tomb can be seen here. Some of them have been colourized.

The description says

3 January 1924 | Harry Burton's photograph records the intact necropolis seal and cord fastening (Carter no. 238a) on the third (of four) great gilded shrines surrounding Tutankhamun's sarcophagus in the Burial chamber.

Two photos seem to show doors like this.

January 1924 | Howard Carter opening the door of the second burial shrine (Carter no. 237), in Tutankhamun's Burial chamber.

4th January 1923 | Howard Carter (kneeling), Arthur Callender and an Egyptian workman in the Burial Chamber, looking through the open doors of the four gilded shrines towards the quartzite sarcophagus.
