I must confess that I don't have a new enough stamp catalog to check this item, which I found among a bunch of stamps to soak off paper.

There is a distinct difference between Stamp #1 and #2, both in colors (black vs. gray "2007") and boldness in brown color (in printed word "FOREVER") as well as the perforations at the LH straight edge side of the stamps. I suspect these are simply from two different types of booklets and/or multiple printing companies involved in the process, but I am just not sure.
Can someone help identify these modern varieties?
Thanks.
