Digital BW, The Print

Just Adding to the Mix:

for 22*30 artwork

Would go with Swiss corner clips + foam board and Mat board 

I did some numbers and Blick Roadshow 3-in-1 Display System
is quite a good deal if bought for in more than 25 pieces... 
Save 10 bucks

But the opening of the mat is 21.5*29 inches aspect ratio of 1.34 

since I shoot 35mm the aspect of 1.5 

I would have very ugly spaces in between darn.

I guess I got to cut my own mat then. Is it difficult without expensive tools?

I think you could mount on deep-cradle clayboard for 16*20 / 25usd +-
