I have a Sascha Maurer poster from the 30's or 40's that is an advertisement for Gregg Skis. All I've been able to find out about the Gregg company is that they were one of the three major suppliers of skis for the 10th Mtn. Div. during WW2. and one of the owners joined his brother to create Hart skis. Does anyone have more information? Thanks, Bill.
