My first A&G - trimmed?

[ASF123]

Hello - I'm reposting this from the March Pickups thread because it understandably got lost in the cavalcade of awesome cards...

I just got my first 19th century card - A&G Keefe.

I don't have any reason to believe it's fake, as the eBay seller has several positive feedbacks for selling other A&Gs. There were multiple other bidders, and the final price was not unduly low - maybe 10% lower than I had expected. The print dots seem consistent with the tobacco cards I have, and it passes the black light test. But I don't have any other A&Gs to compare it with, so please let me know if anything makes you think it's fake. The stock feels quite thick and sturdy, more so than T206s for example.

One issue is that it measures 1/16" short of 1.5"x2.75" in both directions. Can A&Gs have size variations, or is this one likely trimmed? The right edge looks a little crooked/bowed in the photo, but it seems ok when I line it up against the edge of a top loader.

Any help is appreciated, thanks!
