This nice, big Lost World poster can be found at K-mart in 2014. K Mart usually has a poster selection somewhere near the toys. It is like a large metal book where the pages are posters. You can flip through the display. Under it, there will be a numbered bin so you can find the right poster roll. In this case, it's #27.
The poster is pretty cool, it's got Sonic jumping over a part of the twisty Lost World landscape with all of the colorful Deadly Six in persuit. The logo is rather large at the bottom.
