68 Signatures of Famous Artists

The signature is the authentication of any valuable artwork!

The value of an artist signature in art is undeniable. It attests to a work's authenticity and officially declares to whom the work belongs, hence adding full value to an artwork.
Some artists sign with their complete name, others with their initials or just a symbol. We have to bear in mind that numerous artists changed their signatures over the course of a lifetime and that each individual signature is naturally a little different. 

This compilation is an ongoing work, consequently, more artists signatures will be added in time.
