This collection is known simply as the Flower Sketch Collection.
Originally it was a hand drawn sketch which used hatching techniques of maintaining a horizontal fashion to create the texture.
Applications of different artistic techniques led to the creation of the collection, through adapting the sketch digitally 40 different times.
Prices vary, with the lowest selling at 0.0005 and rising up to 0.0025 ETH.
All sales include a signed version of the original hand-drawn sketch.
