This image is on a Goosebumps discord server. It appears to be a signed Tim Jacobus print of a Goosebumps Gold cover, for The Haunted Mask Lives! I haven't been able to actually find the eBay page for this print, but by the looks of the image, it's selling for about $1,500.
But, man, is that what the cover design for Goosebumps Gold was going to be? SO. COOL.
Maybe we should see if we can find the eBay page to get a closer look.
