Lot of 8 Official WW I Signal Corps. Wartime Photos

Lot includes a captured German 135mm cannon, directions on a wall to various Belgian villages, a field hospital topped with a lighted cross (?), a color guard, a commandeered chalet (?), a bombed area with a long truck convoy in the distance, & bombed villages.

Photos measure 8.5" x 6.5" and are all stamped with the Signal Corps mark in lower left-hand corner.

I believe most of these are from Belgium and/or France

Photos 6-8 show identifier numbers inscribed in pencil on the backs.

Please use zoom features on photos for more detail...

Thanks for looking!
