We always consider safety first at The Cloud Appreciation Society. That is why we recommend all cloudspotters display one of these stickers in the rear window of their car. It will warn other road users to expect vague lane changing and sudden pulling over when there are interesting cloud formations above. This Cloud Appreciation Society window sticker is printed onto white vinyl with the sticky side on the front so they face out from the inside of a window. It’s the perfect gift for a driver whose head is in the clouds.

Sticker dimensions are 150mm wide x 108mm high.
