# Electronic Autograph (e-autograph)

In the digital realm, the concept of an autograph can be translated into a digital signature or verification method that serves as a mark made by an artist as a form of personal endorsement.

The autograph is the act of making the artwork authentic and unique. That's when a simple file becomes an original and authentic copy.

Here's an example of how an electronic autograph could look like:

> Me, **\[Name] \[Surname]** the author, identified by my passport, endorse the following facts about my artwork **\[Name of the artwork]**
>
> * **\[Preview image]**
>
> * Minted as NFT on **\[XYZ]** blockchain in the collection **\[collection id]**, as a token **\[token id]**
>
> * The creator of the NFT is identified by the wallet id **\[author's wallet public key]**
>
> *<mark style="color:green;">signed by \[Name] \[Surname] on a compliant e-signature providing service</mark>*

It's important to understand that without an autograph a picture is just a file. One can take the same picture make [EDA](/fundamentals/encrypted-digital-artefact-eda.md) out of it, put it on blockchain, even sell it. However, as long as the author of the artwork hasn't blessed it with an autograph - that picture is not worth an investment.
