Not familiar with the Marque, but at first glance, it seems like it could possibly be a lower end 70's bike boom product, so be careful that you do not pay too much for it....
Do you have any other pics you can post up, especially the rear derailleur and fork crown area, which we can use to make a better assessment of the bike?? A full drive side side view pic of the bike would help too.
