Pigs in space checking

[nanochess]

Hi. A month ago I got a cartridge of Pigs in Space.

 

Various people said that the label looked pretty unique and I though it was simply a Taiwanese.

 

However I was curious enough to extract the PCB and it looks like original, so I think simply it has a homemade label.

 

Just I need the confirmation from someone familiar with Atari PCBs.
