Sticking with a food theme, a Starkist Charlie the Tuna phone. The 70’s had such awesome food mascots.

Twinkie the Kid
Okay, not really a toy. but i ate a lot of Twinkies in the 70’s and this Twinkie holder from the 70’s is awesome.
ERTL Die Cast Super Heroes
I love die cast figures and very few companies do it better than ERTL, from their Star Trek ships to these very cool Super Heroes.
LocBlocs Laser Tank
As a kid, I spent more time playing with Legos than any other toy and especially loved the space kits. After my family moved abroad it was much easier to get Tente and LocBlocks, so I ended up with a pretty mixed set of building bricks. I still vividly remember getting this exact set and building it for the first time. 
Space Laser Flight Game
For science fiction fans, the 70s are a golden age. We had Star Wars, Battlestar Galactica, Buck Rogers, Star Trek and a legion of other shows and movies. And we had electronic toys and games like never before. Consider Space Laser Fight, a simple LED game that is barely more than a fire and dodge game. Not much to look at by today’s standards, but you have to love the box art. 
Mork and Mindy Figure
For Easter, a tangentially related toy. More from Ork, the other Alien that came out of an egg.
