I love comic books of old.  They've been around in the US since the 1930's.
Do you like Spiderman?
I do like Spiderman!  I love the speech bubbles in comics, and the characters and character development via panels.
When did they begin adding speech bubbles?
They have always existed in comics.  It's a key component!
When did Marvel start producing?
Captain Marvel was created in 1939.  Marvel Comics existed before that.
Is Captain Marvel like Captain America?
