Stanley Lewis Litography.Repair??@!!

Picked- up this signed Lithography by Montréal Artist Stanley Lewis @ auction not long ago.
It is Titled '' Emprisoned Poet'' # 25 of 45 made.

Lewis passed away in 2006, he was well knowned in The Montréal, had His studio on top of a Jewish Funeral Monument Maker on The Infamous St-Laurent Street right across from Schwartz's smoked meat in Montréal.
It measures 18'' X 24'', there is a Tear in the paper which is very thin and fragile by the way.
How should i go about repairing this? I think it is worth getting done and properly framed.
Does anyone know or can recommend a place here in Montréal where is could get this fixed properly?....i know it might be a long shot but that is why forums exist .Thanks to any Input or advice from all.

 

If your going to keep it I would repair it but if your going to re sell wouldn't bother. Here is another one of his signed lithograph on etsy

I plan to keep it, wondering how much the job will cost though!

 

You could try using this Lineco tape or something similar to hold the pieces together on the back. The tape is archival and can be removed without damage.
