I recently interviewed and brought both my LogTen Pro book and my originals. They never asked to see my originals. I scanned all of my original endorsements, arranged them on a few pages, and had them in the back of the LTP book. The pilot doing the tech interview commented on that, thought it was a great idea, and that turned into a side discussion on some of the endorsement features within LTP going forward. I used the Jeppesen Pro Pilot format and bought a binder off of Amazon - it was black and a linen/bookcloth type material. This was my first 121 interview so I obviously did not need to worry about adding any extra columns such as TPIC yet!
