The Sonic Mouse Mat was a prize given away in Sonic the Comic. The mat contains a running picture of Sonic the Hedgehog (drawn by Carl Flint) on top of an abstract green background. The current STC logo could be seen in the top-left.
The mouse mat was given away to people who featured in the Issue 165 of the Photo Zone. It was also an incentive to subscribe to future copies of Sonic the Comic.
