Elizabeth "was one of the beauties of her age," with classic English Rose looks - blonde hair, blue eyes, and fair skin - the quintessential English beauty of the time period. She was also apparently quite attractive in her character. Henry was reportedly tall, slim, dark haired, and handsome in the prime of his life. At the time of their marriage, they were probably thought to be the perfect couple. They were young, beautiful, and seemingly pure of heart. They were the founders of a new soon-to-be powerful English dynasty, and they were immediately a success. During the course of their marriage, Elizabeth would give birth to eight children - four of whom would live. Arthur, Margaret, Henry, and Mary would be those lucky four and would all make impressive marriages - though Arthur would not live long enough to take over the impressive dynasty that his parents had created. Instead, it would be the younger son, Henry, who would become the next Tudor monarch - the notorious Henry VIII.
There are virtually no details that I can easily find about the wedding ceremony between these two important figures, but from what I've read, the ceremony was happy and grand - as would be expected of a brand new monarch and his bride. There are many more details about these two after their wedding - with their children and their seemingly perfect marriage. Of course, in this time period, no marriage was perfect, but this one seems to be a pretty good model for future Tudor marriages.
Elizabeth died in 1503 after catching the nasty childbed fever infection from giving birth to a sickly daughter who died soon after, Katherine. Showing the love between the married couple, it was reported that Henry VII genuinely mourned his wife's death. According to one account, he "privily departed to a solitary place and would no man should resort unto him".
Whether or not Henry VII's and Elizabeth of York's relationship was the 'perfect' Tudor marriage, it is clear that they left an impression on the Tudor dynasty and on their most powerful child, Henry VIII. Personally, I find this marriage to be quite an interesting one, and I plan to do some more research on them - especially Elizabeth, whom I think is one of the most ideal Tudor women, according to the things I've read and heard.
Happy Anniversary, Henry & Elizabeth!
