I agree Gyruss

The Bertolino version is vectorized but The Japanese is not.
I -think- they are quite similar but I'm not sure if the sizes are exactly the same. at least the colors are different and as mentioned, I think the Japanese one has one extra color.
Indeed we have a duty there.....I was hoping Mr. McGyver would bring his magic scanner one day but there is no hurry. I have not the right scanner nor the skills.
For the colors, there are Pantone numbers on the original peace of artwork that is on that Japanese website.....not sure if all colors are listed there.

Side art to compare colors....note that this was in direct evening sunlight so colors look a bit more yellow:

They clearly didn't use the blue color for the outline of the space ship. However judging by the Galaxian logo on that Japanese picture the other colors are spot on !
