You know, I own almost 16,000 posters now (15k plus all the doubles and triples and more) and my collection begins with the 1940s and ends in 2020. I have a grading system of what I accept and what I don't. I want mint from 1980 on, rolled from 1984 on, DS from 1988 on. Before that, I accept some pinholes, small, small tears, no linen ever, etc. I've made a lot of mistake since I started collecting 18 years ago, and I've learned what's important to me.
I think we all have our pet peeves and I feel I wasted a lot of time going through lesser quality posters at Emovie.
