Welcome to our inaugural edition of #AISwimSocial, a roundup of some of the best aquatics imagery shared on Twitter. This month, we have everything from an image of a swim club dating back to the late 1800s to an abandoned waterpark. What's your favorite?

If you're sharing inspirational, interesting or insightful images on Twitter, be sure to use the hashtag #AISwimSocial for a chance to have your post including in an upcoming edition. And make sure to follow @aquaticsintl on Twitter.
