I found an interesting jigsaw puzzle

When I was in London last week

It was a thousand piece puzzle

But the puzzle did not have a subject

Are you telling me that it was not illustrated

It was not a landscape

Or a bunch of beautiful flowers

The puzzle lacked a subject

It was a rectangle of light blue

A colour field without an obstruction

When I asked about this puzzle

I was told that when a conventional puzzle

Is reconstructed one uses the illustration

As a reference no matter the subject

This is where these other puzzles differ

As there are no known references

The puzzle is completed using a different method

These new jigsaw puzzles involve geometry

As they require an understanding of shapes

Spatial relationships and how the individual pieces

Fit together to form the whole

Sometimes the most simple of ideas

Are the most challenging and difficult

Do these new jigsaws come in different colours

Yes they come in various shades of blue

Klein Blue Titian Blue Cambridge Blue

Greens are planned followed by reds

The chap at the Tate also hinted

That Black Whites and Greys

Were also being seriously considered
