As has been the case since the first Marvel movie that's been released, Mr. Stan Lee has had a cameo in every single MCU movie (at least, that I'm aware of.)
This was true for this film, and shouldn't be considered a spoiler to anyone. We obviously see him as both a minor character and he has a speaking role, and the scene is pretty obvious. However...
When we see Scott (Ant-Man) come out of the quantum vortex, we see him running around the city until he gets to the memorial garden with all of the local names of the people who've vanished, trying to find the name of his daughter.
Looking through these names, I noticed that on the last tablet there were multiple names ending in "Lee", however, I couldn't scan all of the names fast enough to see if "Stan Lee" was one of them. In my opinion, it would have been an excellent place to have given Mr. Excelsior one last cameo, considering he's passed away wand this is considered the end of a rather long story arc.
So, does Stan Lee appear in this portion of the movie as well?
