Digital BW, The Print

Hi,
I'm wondering how I should sign a print that is, say, the first print of the second open edition .... I'm forever looking at prints and thinking I could do better and should start another edition. 

How about 2nd ed 1/open? It sounds a bit long winded - is there any shorthand method that people would understand?

thanks,
Richard
