All of the proceeds from the sale of the apples, which went on sale earlier this month at some of M&S's top stores, will go towards providing specialist treatments and research for Great Ormond Street Hospital patients. Jazz was chosen to help encourage people to buy the apples because it is M&S's most popular variety.
The sun tattoos were created using a delicate process that saw some areas of the apples' skin purposely deprived of sunlight.
Baxter placed a double paper bag over each of the apples to stop the fruit's natural colour developing. The paper bag was then removed a month before harvest and a layer of tissue was put on the fruits to expose them to the sun without them getting sunburnt.
The tissue paper was left on the apples for just a week - and transfers of the logo were put on the skin of the fruits as soon as the tissue was removed. The transfers were left on the apples as their colour developed and were removed when the fruits were ready to be picked.
Meanwhile, all M&S's class 2 Jazz apples that cannot be sold in its stores will be donated to the Great Ormond Street Hospital Children's Charity.
