So I'm relatively new to comic book collecting. I've been reading and collecting on and off for the past 5 years, mainly by myself with no one really guiding me. That being said I do own over 700 comic books and a couple of TPB. I just had a few questions and figured I'd ask here for help.
1) What exactly are ominbus? I figured they are just collections of older stories or something but didn't know if it was more than that.
2) I have read a few of Frank Miller's TPB for Daredevil and want to read more, but what is the difference between the Vissionaires TPB and the regular big Frank Miller's Daredevil TPB?
3) For variant covers when do you know it'll be worth buying?
I'll probably come up wit more later but if you guys could help me with these questions it'd be a big help to me. I know you guys probably have a lot of opinions on number 3, so I'd love to hear them all. Thanks
