The Adventure Comics #210 in context
Why collectors care
The first appearance of Krypto the Superdog, cover-dated March 1955, in a Superboy story. Krypto expanded the Superman mythos into the "super-family" era and remains a recognizable character across animation and film.
How to identify it
Adventure Comics #210, 1955. Krypto debuts in the Superboy feature that headlined the title at the time.
Common mistakes
Confusing Adventure Comics issues, which carry several unrelated keys across a long run — #247 (Legion) and #260 (Silver Age Aquaman) are also in this catalog.
Grade considerations
A mid-1950s book with thin high-grade survival. Cover gloss and page tanning are the usual limiters.
