Sadly it's not possible within the website's preview images to display the actual detail in the drawings or the print quality. everything from how they've been scanned, to choice of paper, to using inks that in a normal display environment will out live you, have been taken into consideration.
However, if you're not delighted in the quality of your print, as long as the print is returned in a fully re saleable condition, I'm happy to refund the purchase price (minus postage costs). You are also liable for the return postal cost.
In the rare event that your print is damaged on it's way to you, please contact me as soon as possible, so that I can start putting it right.
As a small business, I trade entirely on reputation, as such it's important to me to treat my customers in the same way that I would want to be treated.
