Mary Blair’s wonderful designs for ‘It’s a Small World’ formed the basis of one of the most beloved of all of the rides at Disneyland. I learned recently, that within Disney Imagineering, the ride is referred to as the ‘Rainy Day Project’ as this was the concept behind Blair’s colourful graphic treatment of the environment – imagining a mother’s cut-paper designs, created to amuse her children during inclement weather.
