Vintage Fabric 1970s? 80s? Spectacular Blue Purple Base w/ Intricate Flowers Liberty? Cotton Lawn 92cm Wide

FABRIC INFORMATION
Fabric: I have spent some time trying to find information on this spectacular fabric, but I haven't come up with one thing! It's a cotton lawn - beautiful quality - with an intense colourway of a blue/purple base, pink red and orange indienne style flowers and leaves and black lines with tiny abstract shapes. Absolutely top tier cotton with detailed printing - hence why I question whether it's vintage Liberty. 
Era: unknown - leaning towards the late 70s or 80s. 
Condition: unused, unwashed
Width: The fabric is 92cm wide selvedge to selvedge
