Up for sale is one of the most rare Mac Miller signed items to hit the market. This is the signed vinyl/album  of Mac's iconic "Blue Slide Park" album with a "Thank You" inscription. This is authenticated by Beckett (see 3rd photo for hologram) and will come with a full Letter of Authenticity from Beckett as well. Please note this was just authenticated on 5/8 and it takes about 30 days for the letter to arrive, should it sell before I have the letter, the letter will be sent after once received by me (item itself is hologram of course).
