REAL OR REPRO? Awesome Flea market find 30x40 AMERICAN AIRLINES TRAVEL POSTER

Majority are smoke free dust free no rips no tears, pictures of these posters were all taken today, posters are all rolled, I found these today at a local Flea and was elated .

Heres what I know 60s , 70's American Airlines pictures (artists vary) cities vary, also considered poster / travel art, I would love to learn more or even can share these items. 30" x40" or 40" x30" large retro style

Any collectors have any info to ask or info to share I'd be delighted
these were the first 3, I'll post another 3 as well. I love what I don't see everyday and I love the story behind the decades and quality of teh color and the paper
thanks
