The certificate, measuring 140 centimeters long and 30.5 centimeters wide, had been kept by the Sim's family who settled in Pado-myeon, Dancheon-gun, Hamgyeongnam-do. The document was issued according to the newly adopted reward system with a view to enhancing the numbers and status of the founding contributors in the newly founded dynasty–more than 1,400 people got rewarded from 1392 to 1397. Details as such were not recorded in Annals of Joseon until this decree was verified.
Significant features are the mixture of linguistic usage such as the Idu script, printed by wooden movable types and a rare printed document from early Joseon period.
