The 9 Oz mugs are among the most character decorated of all.  With more consistent diameter and height it makes for a better canvas than most other mugs.  It is actually more difficult to find a plain white one than a decorated one.  There were some fired-on colored 9 oz mugs made but I believe these were generally made only after the Fire-King era ended.  One exception is the black zodiac which is very hard to find marked Fire-King.  The vast majority of them have only the Anchor Hocking symbol.  Marked with the “Oven-Proof” embossing, you can count on these mugs being from the mid to late 1970s.

The handles are a little different than a D-Handle mug, as well as the bases.  These mugs will stack.

Lastly of the Snoopy mugs, there are two in the set not pictured.  On the Mug Shapes page is the “I Hate IT When It Snows On My French Toast!” Snoopy mug.  However, the newer set of mugs showing Snoopy riding a bicycle, or “Snoopy for President” for example are later Anchor Hocking mugs, post 1980.

A nice set of mugs with handsome patterns, none of which are very common.
 

The Friday’s Child mug is one of a set of 8.  7 days and one general birthday mug, all of which are fairly uncommon and a set would be a small treasure.  The Zodiac mugs marked Fire-King on bottom are very hard to find.

The paradise bird mug is very pretty but unfortunately not marked Fire-King.  The Strawberries mug is nice but shows some color loss.

I Think I’m Allergic To Morning!; Curse You Red Barron! (the most valuable of these mugs.  If you find one with an orange roof those are even more valuable); At Times Life is Pure Joy!
