This week’s Flickr #TBT is all about things that radically changed our lives. We want to see old pictures of items or ideas that were a totally new discovery to you, something #Revolutionary! Was it a certain historic moment, a new fashion style, a color tv, new cellphone, camera or your first computer that amazed you? Share your favorite pics on Twitter @Flickr adding the hashtags #Revolutionary and #TBT or on our Facebook post, and we’ll show the best ones next week on the Flickr Blog.

And get to know the Flickr Commons! This photo “Amphibious bicycle” is from Nationaal Archief – https://flic.kr/p/7oyQ1s
