Waldo attended their wedding
“Where’s Waldo” was a well-known game back in the day. Players had to look for the man with the glasses and the striped sweater hidden in a vast ocean of people. In this image, he´s not so difficult to find, but we are curious to know why he is at this wedding.
Once he’s been spotted in the background, perhaps the wedding party can ask him why he’s there, and if he brought a gift. Although no one seems to notice his presence. he does add some color to the background. Maybe he’s related to the newly married couple. These and more questions will never get an answer.
