Often we have requests for group caricatures with a LOT of additional people. Generally (though not always) the price has the client settling for an artwork that is more price attractive.
Here is one example. How to include 143 other people in the artwork, without drawing each one and the cost going through the roof? The answer of course is a montage. This montage took six hours to assemble, rather like a jigsaw puzzle.
The art then proudly featured front and centre.
