I just took a look thru the gallery and didn't see these images of Cap anywhere. From FOOM #8, circa 1974:

Bucky & The Falcon too:

in glorious black and white

10 points if anyone can name them all.theres a few i don't recognise.

Off the top of my head,

Drax, Airwalker, Baron Blood, Jackal, Lillith, Ancient One, Green Goblin, , host Rider, Bucky, Egghead, Baron Zemo, Bloodstone, Giant-Man, , Jacosta, Foolkiller, Swordsman, Zombie, Spirit of '76, Red Guardian, Patriot, Miss America, Zuras, Mimic, Pip, Whizzer, 3-D Man, Spitfire, , Satana, Shang-Chi, Baron Strucker, Black Knight, Banshee, Korvac, Mantis, Destroyer, Dracula, Count Nefaria, Man-Wolf, Captain Marvel,
It, the Living Colossus, Gamorra, Changeling, Nighthawk, Phoenix, Nova, Thanos, Thunderbird, Torpedo, Thunderbolt, Son of Satan, Yellowjacket, Marvel Boy, Toro, Adam Warlock, Morbius, Darkoth, Nebulon, Spider-Woman, and Omega.  I think that the hooded guy with the fedora is Death-Stalker, but not 100 percent sure, and I don't want to just go cheat.

Edited to add Terrax.

The dead guys have arms crossed, and the retired guys have them at the side.  Nice touch.
