The inspiration for this series of geocaches was Jose Monkey. He is a vlogger who finds people from videos they post of themselves from around the world, in which they challenge him to find where they are. If you want to see what techniques he uses view his videos in which he explains how he locates the individuals.
View the video in this link. Where's Wally - May Spot Wally in the video (red and white shirt, hat plus glasses). Go to the location where Wally is stood and search for a container in which will be the final coordinates. Then go to that location and look for the cache which contains May of the Wheres Wally calendar. This is the log sheet, which you must sign in order to claim a find.
