How to get the second photo frame on the left side of desk wall?

I'm going through my playthroughs and I was surprised on my 5th run through that I see a 2nd photo frame on the wall above my desk. We all get the standard one to the right side that we can pick a 2D art of one of the girls for. Now I see this playthrough has a 2nd to the left that allows for a choice of other 2D art pics. This is great, but I completely forgot when or how I got this. Does anyone know the trigger?
