A slogan tee with "It's Boom Time!!!" written in big green font was released in fall of 2015. It's either black or quite a dark navy blue short sleeve tee. This is a kids/teens size item. The square contains a CG background from the show and you can see hand on hip Sonic, ready standing Knuckles & winking Tails (though he is a bit small and sort of in the background) The Boom logo sits at the bottom right corner. Is "Boom Time" watching the show?
Where was this tee sold?
