Jen❤️

This is a rare mostly-intact message from a random civilian unaffiliated with any subreddit. Jenny's fiancé was originally trying to place this under the pink and purple heart in the Madoka artwork, and the Madoka team reacted by erasing it - but reached out to the user in question and negotiated a transplant. The text at this location originally read "Jenny ❤️". The Madoka team kept it tidy as part of a neighborhood-watch effort to deter vandalism and invasion, and negotiated with Turkey to shorten it when they wanted some of the space above for Hayir. The final form is unfortunately mildly vandalised.
Previously at this location was the message LDSConf for the Church of Jesus Christ of Latter-Day Saints annual conference.
