Overall view of the aft (active) side of the Gemini heatshield subjected to reentry-type temperatures. See the NASM collection ID #A19781814000 page, which notes that this heatshield "may have been installed on Gemini 2").

As seems to be common, a number of cores have been removed from the heatshield (which are even more obvious from the opposite side), some of which have been replaced with similarly-colored cores (although there are still some empty holes).

To see what a Gemini heatshield looks like after a core has been removed, see this photo on Gemini 12 at Adler Planetarium.
