Be careful...it's very easy to spend a lot of $$! We have several lines that we have built up over the years and we are well known for the selection. Among the favorites:
Great Arrow Graphics (Hand pulled silk screened notes)
Brush Dance
The Art Group
Design Design(Funny)
quotables
KOKO NY
and a new local line that is being introduced at the NYC show "Lola Says"
I have probably 5 or 6 other lines, but there are so many out there...we tend to go with a contemporary look, lots of art cards and blanks that are frameable...you have to build your own look.
We started with Great Arrow Graphics 12 years ago and still have them, and we added 1 or 2 new lines every year, but I'm maxed out on space now. 1 rack (36 pockets) can easily hold over $500.00 in inventory. Try to find companies that will sell to you in half dozens until you see what moves for you...try 24 pockets to start if you can do it. Many companies will give you a rack if you fill it, but that usually means 36-48 pockets or more at full dozens.
