Yes, they are a lot of fun! If you examine them, Coolige includes many amusing details and I suppose some could point out satirical comments on the politics of the day.

Being a 12 month calendar and only nine poker themes extant (?), several other dog scenes are included. January's "New Years Eve in Dogville", A dog baseball game, "One to Tie, Two to Win" in August, and in December, "Dog of a Bachelor" with a self-possesed and satisfied "lone wolf" of a dog in his easy chair, smoking with cigars at hand, a glass of beer on the table and the day's correspondence being perused. Looks like TCR #1 is handy beside the fella as well.
