Here's me with three boxes of nice some what vintage thread (the small bobbins (spools) are plastic not wood, so they cannot be *that* old, and have no idea what sort of thread.
Boxes only state "Tubino Fil Lustre A La Cle - Thiriez Lille-Paris.
Though French can make out it's cotton (ok, so that was easy), but not sure if this is embroidery thread or sewing thread. The cellophane wrapping around each bobbin is intact, and would rather not open one up just yet.
Clues anyone?
