Ask a question

A beautiful visual exploration of the strange sequence of numbers, nowadays called after the great 12th century Italian mathematician, Leonardo of Pisa, better known by the abbreviation of the Latin for ‘son of Bonacci’, Fibonacci. The Fibonacci sequence crops up in the most unlikely places in nature and society. The relationship between the sizes reflects the golden ratio, which underlies the Fibonacci sequence.

Designed by David Lawrence, d/dx art prints are created on heavyweight Canson Infinity artboard produced at the centuries-old Arches paper mill in France. This superb artboard is acid-free and uses no optical brighteners to degrade over time. Ultrachrome K3 inks provide vivid colours which will last without fading for many decades in normal conditions. The robustness of the paper makes DIY framing a simple matter.

The prints are standard European A4 (210*297mm) or A3 (297*420mm) in size. They are packed flat in crystal envelopes with cardboard stiffener and posted in a rigid container via Royal Mail first class.

Prints can be initialled "D." using the customization option at the time of purchase. Just add 'Initialled please' or something similar!

Additional

The colours you are seeing on your monitor are inevitably not precisely the colours you would see if you were looking at the same design in printed form. There is simply no way around that, since the internet places limits on the range of colours that can be displayed and, even if that were not the case, every monitor is subtly (sometimes wildly!) different in the way it displays colours.

But you can be reassured that the quality of our equipment is such that colours and quality are consistent over time and the print you receive will be identical to other prints sold in galleries and art fairs to buyers who have every opportunity to handle and assess them.
