is this really a reubens?

So, I have a print that is signed Reubens. I know that Reubens was fond of a painted light study he produced and that he actually created an engraving from it. I have posted pictures but am afraid to take the print out of the frame since it has been folded in half and has a small tear. The print was cut down so there are no register marks. It is also very badly faded.

Of course, the identification is wishful thinking on my part but I would like to be sure.

 

Of course it is Reubens but the question becomes what state the print is. My gut reaction is that it is a modern copy based on what I can see of the paper but this picture is not definitive. I guess I would like to see the entire sheet held to the light. In the meantime, here is a museum copy for comparison.

Thank you for your fast response. I held the print up to the light and I can see through it. There seems to be a watermark but I cannot quite make it out.

 

Take a loupe or magnifying glass and look for pixels.

 

The reason to hold it to the light is to be able to see laid and chain lines indicative of early papers. Here is what it should look like.
