Sprite Stitch Board!

Morning
I am looking to get the sprites for pokemon red/blue. I want to do the 151 original pokemon but trying to find their sprite form and not their character form is quite hard.
Does anyone know if they have been found/ know where to find them so I can put them into a picture?

Thank you

By sprites, do you mean the overworld ones? And did you want the original Red/Blue, or Fire Red/Leaf Green? Here are a couple of ones that I found from both.

Red/Blue Colored Pokemon
Red/Blue Black and White Pokemon
Red/Blue Overworld Pokemon Not all 151
Fire Red/Leaf Green Pokemon
Fire Red/Leaf Green Overworld Pokemon Not all 151
