Actually, I'm not sure how rare this photo is, but I haven't seen it in many other collections. It shows the NY Times newsroom on the morning of April 15th. According to the clock visible in the background the time is approx 10:30am.
I see a 15 April on that wall calander but no year. The day itself is too long to be "Monday" in my opinion. The clothing, equipment and furnishings are contemporary to the period but that covers a range of several years.
Yes, Eric. The "15" looks painted on. Neither figure aligns with the angle of the rest of the type on the calendar, and they don't really align with one another either. There is also something odd about the proportions.....
The base of the "1" is 'parallel' to the frame of the photograph. It should slant downward, slightly, from upper right to lower left. The "5" is a bit more convincing, but seems crowded by the "1". I'd say that at least the "1" was painted in later.
"The New York Times did not alter this photograph digitally in any way. Basic cleanup, to remove dust and scratches is all that was done. It is possible that years ago the original print was enhanced using black or white Ink, a practice that was common in the first half of the last century. However there was no indication of that on the back of the print. The limited information from the back of the print was embedded in the file sent to you."
