When Upper Deck released Upper Deck SPx Football in the fall of 2009, card collectors were introduced to the first ever Shadow Box card. These innovative three dimensional trading cards were a massive hit within the card industry. Like any successful invention, the competition quickly followed suit and began adding this technology to their product releases. Upper Deck Authenticated has taken the 2.5" x 3.5" trading card technology and transformed it into a 16" x 20" piece of wall memorabilia. Joe Montana has signed many pieces of memorabilia over his storied career, but he has never signed anything quite like this 49ers three dimensional Shadow Box. The outer acrylic layer features an image of Montana readying to pass in his home uniform. The middle signed layer shows Joe Montana throwing the ball while being hunted down by the Los Angeles Rams. Montana's shadow is revealed on the back layer, which houses an image of the LA crowd. This multi layered shadow box contains images on each layer with the all-important signature housed on the middle clear acrylic sheet. 49ers legend Joe Montana has signed his name in black paint pen. The layers of the shadow box are housed in a black metal frame making the overall framed dimension 20.5 x 2.5 x 16.5. The 3-D Shadow Box Collection by Upper Deck Authenticated is sure to be fan favorites and the topic of conversation when viewed for the first time. Montana' signature was witnessed under UDA's Five-Step Authentication Process.
