Yesterday, today and tomorrow

These are variations of four large panels I have recently completed for a magnificient house in the Tarragona area.  They are four panels 195cm high that can be assembled in a variety of ways.   Here I have included four possibilities...
The work is called 'Yesterday, today and tomorrow' which comes from the name of  a shrub that grows in South Africa that bears white, pale mauve and dark mauve flowers on the same plant.
