I am OK with limited edition prints, hand pulled by the artist, signed and numbered, also monotypes, etc., and have a few.
I use the salon style approach to displaying artwork and have ten foot ceilings in my Victorian home, so have floor to ceiling artwork and wall to wall, about 900 of my 2000+ painting collection are on display at all times. Each to his or her own aesthetic, though.
I never suffer from a lack of things to look at and am constantly rediscovering my collection. I took a quick look for some images of my house but couldn't find any. I will post some later, if I find them...
