Hello,
I'm a UK based artist specialising in painting. My favourite medium is paint on ceramics or glass, but I have done a lot of work on paper, wood, and canvas as well.
I run a business selling hand painted home decor, including a service to create paintings from photographs. As such, I have experience in accurately reproducing images, and would be happy to do a version of Sophie the giraffe for your height chart.
The price I have quoted includes postage of a paper chart in a tube ($25 for signed and tracked postage). If in fact the chart is to be un-rollable, like on wood, the postage will be an extra $55 (yikes!). I'm happy to do this if you are!
Have a great day :)
