Yes, they celebrated the Yuletide in the Old West...
...although technically, this was the contemporary (1940s) West!
Though the series started with a standard 1800s Old West setting, after creator Bill Everett left, the new writer, Bea Holmes, and artist L. Kennerly, began inserting contemporary references and technology.
By the time of this tale from Target Comics #12, the series was firmly-set in the present-day.
In fact, Bull's-Eye was recruited by the Army for special duty to prevent sabotage at Western bases in the very next issue!
We're taking next week off, so we'll see you in 2012!
Happy New Year!
