Alberto Martini postcard

Hi looking to purchase this postcard don’t know if it’s a repo or original? Have looked at others on google & this one has faint lines on back the one on google doesn’t? Any help thanks Gavin

To determine if this is an original or reprint, consider the following:
1. Medium and Surface:
Original: Original paintings are typically on canvas, wood panels, or thick paper.
Reprint: Reprints are usually on thinner paper or cardboard.
2. Texture and Brushstrokes:
Original:
Examine the surface for visible brushstrokes, texture, and layering of paint.
Reprint:
Reprints lack the texture and brushstrokes of an original, appearing smooth and flat.
3. Edges:
Original: Original paintings often have irregular edges, especially if not framed.
Reprint: Reprints typically have clean, straight edges due to the printing process.
4. Signature and Details:
Original:
Examine the signature closely for authenticity. Compare it to known signatures of the artist.
Reprint:
Reprints may have a printed signature, lacking the unique characteristics of a handwritten one.
5. Age and Provenance:
Original: Research the artist and the artwork's history. Look for any documentation or provenance that establishes its authenticity.
Reprint: Reprints might not have any historical documentation or provenance.
6. Expert Appraisal:
Original: For valuable artworks, consider seeking an expert appraisal to confirm its authenticity.
Reprint: An expert can also identify a reprint by examining its characteristics.
For the specific image you provided:
The image appears to be a postcard, which suggests it is likely a reprint.
The smooth appearance and lack of visible brushstrokes also point towards a reprint.
However, to be certain, examine the physical postcard for details like paper quality, texture, and any potential markings that might indicate originality.

Hi thanks for replying

The proper answer would be that it's impossible to conclude 100% by watching an image.
