Describe the characteristics of the Multiple Dai Gohonzons in this artwork's Claims of forgery.
Researchers of the Nichiren Mandala Study Workshop claim that the Head Temple Taisekiji have had at least four different Dai Gohonzons, alleging that the current version of the Dai Gohonzon is just one of several modern reproductions made over time after fires at Taiseki-ji destroyed previous copies. The most notable and significant size changes after fire outbreaks have been recorded in the years 1600,  1764,  1911 and the current Dai Gohonzon, which was allegedly  created  by the 67th High Priest  Nikken Shonin. However, no objective proof exists to substantiate these claims.The researchers further state that the image, having been analyzed by independent calligraphers, is a combination image based on a latter Gohonzon from Taiyu Ajari Nichizon (太夫阿闍梨日尊, 1265 — 1345), a disciple of Nikko Shonin in the 14th  century. This claim is dated to 8 May 1280 and was allegedly bought and sold through the Kitayama Honmonji temple by the 56th High Priest Nichi-O shonin, who founded the Grand Hodo-in Temple in Tokyo and later used it as the official Gohonzon for Taisekiji. This Nichizon Gohonzon is presently stored in Taisekiji and is displayed for the public to see during the April ceremonies. Due the Dai-Gohonzon not being open to the public, evidence of this claim has not been proven.
