Narrative:

Captain was taxiing to runway 25L in mke via runway 31. Tower advised we were to follow company who was on taxiway M. We acknowledged. We started to 'make turn' from runway 31 towards runway 25L when we noticed there was no hold line. We stopped and noticed blue taxiway lights perpendicular to us. We saw company to our right and let them pass us onto runway . Tower then had a dornier 328 pass us for departure. As we were cleared to taxi into position and hold, I looked back at runway 31 and saw a partially obscured by snow hold line. The tower gave us clearance as we were (captain and I) querying whether to contact tower. We did not block taxiway M and were not on runway 25L. We noted this hold line is not depicted on airport diagram.
