Old Bikkuriman Satan Maria, early chocolate version, pale yellow back

I've cherished this for about 40 years.

Among the multiple Satan Maria stickers I own, this is a fairly clean one, but the corners are slightly bent, there's a small brown stain on the upper center-left of the back, and the upper center is slightly warped, so please check the images.

I believe it's from the early chocolate version, but please examine the images carefully and make your own judgment.
The back is a pale yellow color.

It will be placed in a sleeve, sandwiched between cardboard, wrapped in bubble wrap, and shipped in a Nekopos dedicated box.
