Masquerade Masks.

Masquerade masks were used to hide the identity of the person wearing it during magnificent balls. This meant that you did not know the person you were dancing with because they had a mask on their face what hid their true identity.

The idea of a Masquerade Ball goes back to late medieval court life; it was originally designed to celebrate a marriage or mark a point in a royal family.
Masquerade balls grew into semi-public events by the time of the Renaissance, allowing the aristocrat and servant to interact, under the cloak of disguise - their popularity was very much about the freedom wearing a mask gave you.

For the rest of the 18th century these types of masks remained popular, spreading from England across to America; where they also became more relaxed, as guests tried to guess the identity of the person behind the masks.

They then had a rebirth in the late 80's and 90's both across Europe and in the US, when both individuals and business organisations rediscovered how perfect a Masquerade Ball was to add an element of Glamour and Excitement to any Ball or Party.
