Manchester City "Moonchester Shirt" Authentic

Here I'm selling my authentic 2015/16 mascot worn Manchester city "Moonchester" shirt. I have no real way of authenticing this because it was a gift from my best friend who is currently both Moonchester & Moonbeams personal minder and has been for many years. It's got a couple of marks on in which I don't know what they are and could come out easily however I've never once washed this shirt because I've not wanted to ruin it because it's literally one of a kind and that's also the same reason I have no idea on pricing for this so I am open to FAIR OFFERS ONLY! This is an amazing piece of Manchester city memorabilia and I've never seen one before other than on the mascots themselves lol 🤣 If you want the only proof I have, I have images with the mascots myself and of my friend with them both who looks after them both on and off the pitch, if you want it and request it. Thankyou very much for looking at this item and stay blue 🩵🤍
