Microverse was Hasbro's short lived rival to Galoob, who had the Micro Machines toyline. There was only two transformers Microverse sets made, the aforementioned Orcanoch which was part of the Maximals and the Predacon Arachnid. Each set came with two mini figures as well as the transforming base.
This listing shows the box art of Orcanoch as it was being prototyped and has annotations on it which would have been put on there during the design process.
Here's the product description as it is on Amazon.
Amazon wrote:This listing is for a Transformers Beast Wars Orcanoch Killer Whale Maximals Playset box art prototype. These two pieces are Cromalins for the artwork that was used on the front of the box. They are on thick glossy paper and are full sized and not cropped like the box art. One is 9x12 the other is a tough bigger, both show some scratching and corner wear from use and both have marked changes and notations on them. These are amazing one of a king pieces for an already rare playset. One piece is marked August 1996 the other September 1996. A great piece of Transformers history If you have any questions please ask.
The seller has the item listed for $219.99.
