To my knowledge these would have originally come with a small cotton twine in their pupils to hang them on the wall... More often than not these strings are missing. This one has a newer, replacement string. A standard push-pin pushed into drywall allows these to easily hang on the wall snug and flat. Measures 5.5 x 5.1 cm.
