I wanted to post these panel tiers that are from two different Fantastic Four issues that were produced nearly a year and half apart:
Top row: Fantastic Four #132 (April 1973) John Buscema
Bottom row: Fantastic Four #149 (August 1974) Rich Buckler
You can see how seamlessly they flow into one another; of course both issues were embellished by that most extraordinary of inkers, the incomparable Joe Sinnott (as if you couldn't tell). Sinnott's finishes helped maintain a consistent look for the FF from the second half of the 1960s well into the 1970s. It's Joltin' Joe's 88th birthday today, so let's all wish him a great one!
