Don post blood skull question...

I know post made the regular vinyle skull in 1967 which i love my favorite… but when did they make and release the blood skull?? did it come in latex and vinyl was it small or inlarged… what about don post crimson blood skull from the mid 90’s what is diffrent the 67 blood skull and the 90’s besides the year?? are they exacxtally the same is the 90’s version any good or junk or worth even picking up? can you find them just about any where or are they scarice or valueable… what’s the price range that the 90’s blood skull sell for or picking one up? ive seen one but the eyes weren’t cut out still intact versus the original 67 blood skull eye’s cut out… post made so many versions of the skull i cant keep up lol… so if any one has any info on the dp blood skulls please let me know…
