It may be a striking piece of art, but not very accurate. Given an actual photo taken that day, I think the artist is trying to be dramatic and failed IMHO. In the photo below, it almost matches the ground debris cloud and updraft column, but the fireball is much smaller than that of similar test blasts later on, not even the diameter of the column.
At the point in time of this photo, the shock wave has completely dissapated and past the observer aircraft.
As for being PC, history rarely is and warfare is totally unPC.
I was trolling through AWM (Australian War Memorial) related sites and came across this. Recently there have been topics on SteelNavy relating to box art depictions of Allied warships shown being destroyed in battle by Japanese manufacturers.
I personally don't mind these representations as do many others, but I have noticed that some people are offended at worst, or are not that pleased at least.
So, searching out 'AWM' I came across this box art for a famous "wingy thingy" as many like to refer to a/c, and was quite amazed at the audaciousness of it even though it is quite honest. https://amarket-model.com/wa-data/public/shop/products/13/82/8213/images/20431/20431.750.jpg
The artist has captured almost to the instant when about 40,000 people were killed, and the aerial depiction of Hiroshima is quite good and you could almost imagine the 'T' bridge vapourising even if you can't see it. Also the shockwave is well done as it expands on its smashing journey. Perhaps 82 is a little too close to the action but good box art is always exaggerated a little.
The most impressive item though is the title:
'American Nuclear Killer'!
Well, they have got it right but definitely no holding back on the judgement, and there can be no doubt that this whole presentation is intented to be a judgement in the negative (to create sales? well here I am!).
No favours to the USA from the Russians hey, for bringing a terrible and long lasting war to the quickest conclusion possible. None what so ever.
Anyway I very much like the B-29 and unorthodox box art so I'll be adding it to the pile, and I'm curios as to what the AWM thinks about brand. The AWM cannot make money, that is trade like a company, so obviously does it have a trade mark or not? I'll send them a copy and see what they think .
