I remember someone inquiring about the last PFE split. It was on July 1, 1997 a 2:1 split. The stock rallied up to and for a brief period after the split. However not too long after the split the stock corrected. How much of this correction had to do with PFE vs. general market sentiment I can't recall. The link below shows the split info.
Yes the last post split price was about 60 or so, meaning the stock split at around 120 back in July of last year.
