A marvelous collage by Dorothy Wallace-Senft. This poster shows the type of snowflake formation relative to the temperature. Over 400 of Bentley's snowflake images are cleverly used to illustrate the thermometer. Also contains a picture of Bentley at his camera. A great element for the classroom or the room of a budding scientist. Printed

Love it. Had it framed and it’s hung near our back patio door!
