Even though more than 9 actors have portrayed the Doctor, no actor has embodied the part more than Tom Baker. His contribution to the part has effectively made him a permanent part of pop culture.
(Top Box Pic Courtesy of Mike Farence) Mego didn't miss a detail of the Doctor's costume from his hat to trademark hat and sonic screwdriver. Some controversy exists that the head sculpt is actually borrowed from Gambit of the scrapped "New Avengers" line of dolls, although this has never been verified.
The Doctor was one of the only dolls released outside of the UK (Dalek and the Doctor were released in Australia by Toltoys as well), Italian (Harbert) boxes are usually the more commonly found even today and shouldn't go for more than $125-150 MIB
