Is this Base Set Venusaur legit?

Hi,

recently purchased this but some doubts mainly due to the wavy/stitching effect on the yellow bordering around the card, extra nervous because it’s the most expensive card I’ve bought so far.

Can anyone give advice?

Looks good to me :+1:

Hit it from behind in a dark room with a flashlight, could be blue core maaaaybe. Im not great with foil variants yet BUT def real so no worries there.
