I think you're going to have to post clearer photos if you want some opinions. I couldn't say yea or nay. Steve
You know, it's hard to tell with those grainy and blurry pictures, but based on that date and what I think might be a die gouge on the upper part of the "D" on UNITED on the back, that kinda does look like Wexler's DDO #2. I could just be looking at it wrong from the way the light hits it, though, so you definitely need to send a clearer picture.
BTW, that is not an expert opinion since I am no expert, and I guess it's not really even an opinion either since I can't even see it. My eyes still deceive me quite a bit even with crystal clear pictures! lol!
