From left to right:
Maxfactory's Bigfoot, Medicom's Bigfoot: Another Sighting, and Medicom's Female Bigfoot.

The Maxfactory Bigfoot. Made of polyvinyl resin. Made to look similar to the Patterson film's creature.

The Medicom Bigfoot: Another Sighting, from the series 2 set. Made of a more plastic-like vinyl. This one appears to be the creature from the Cliff Crook (toy in mudd puddle) picture. There were two versions a white and a black.

The Medicom Female Bigfoot, from the series 1 set. Like the previous one, it's molded in a more plasic-like vinyl. Obviously, it's sculpted like creature from the Patterson footage in the famous camera turn. Two versions: Brown and Black(pictured).

All of these statues stand around 3" tall, and although small, they are highly detailed. They also come with cards that identify the pieces. They can be obtained for about $3 - $5 each. Well worth the money.
