info on Gitane grand sport deluxe road bike?

[jdscj8]

I just bought a bike for my 3 yr old son at a farm sale, i didn't know that 5 other bikes came with it. They are all old 70's and 80's road bikes. Can anyone give me any info on a Gitane grand sport deluxe road bike, i think its from the 70's it looks to be all original i rode the bike and it rode great. I'm going to sell it cause i won't ride it, but I need info on it first, like what would it be worth, years they made this bike, and anything else
