Alexander Calder litho w/French or Italian Gallery? writing on back?

I found this today at a local thrift store along with a lot of other art & sculptures that all came from 1 home (manager said owner died & family donated everything to make selling it easier).
This Calder's backing was loose & I was afraid it would let the glass fall out so I removed it to try to tape it or seal it (bend staples back better) so it was more secure - and I found this on the back?
Is it from a gallery? (middle set of writing on back says: galerie de varenne / 61 rue de varenne / paris eme - and the last one says something about a exposition tous le jours sauf le lundi/ and a date?)
Is it from the 1960s or 70s or new?
Any information would be appreciated!

PS - what are the 4 hash marks by the frame next to the signature?

 

I think the tips of a few of the lines above the text, where it was folded over.

 

It appears to be an exhibition poster with bits folded over. Galerie de Varenne, Paris. Yeah, here it is. 1973.

Shame it's been folded - if it's lost its value from it I'm going to keep this one, I love his work!
Thank you so much for the help!

 

What was info on back for - could this have been a poster from the show itself?

 

Yes, it's a poster advertising the exhibition.

The name of the exhibition was Tapisseries Inédites, which IM Translator gives as New Tapestries, but I think more literally means (previously) Unpublished Tapestries. Ones that haven't been seen before, at any rate.

Exhibition was open every day except Monday, 2 - 6:30pm.

 

Could it be folded back over and restored ?
I like Sandy Calder's work too.He made a little miniature circus when he was younger-hand sculpted toys that kinetically moved.They were beautifully little things that I'd guess most adults thought were cute and fairly clever-they led to his eventual creation of The Mobile.

 

paper once folded breaks the fibres ....they can not be unbroken..

 

And conservation costs would likely exceed the value of the poster
