Handmade silver tone wrap bracelet with an autism charm surrounded by crystals.  Note: These bracelets are truly one size fits all - don't be afraid to bend the tubes for a tighter or looser fit.   Autism Charm - History behind the Puzzle Piece The puzzle piece logo was first created in 1963 by the National Autistic Society. They explain “that the symbol of the Society should be the puzzle as this did not look like any other commercial or charitable one as far as they could discover. The puzzle piece is so effective because it tells us something about autism: our children are handicapped by a puzzling condition; this isolates them from normal human contact and therefore they do not ‘fit in’.”
