What should you look for at the comic shop tomorrow? I'm glad you asked!
Dark Horse have Beasts of Burden: Animal Rites, a collection of the superb mini-series by Evan Dorkin & Jill Thompson, with the earlier short stories from the Dark Horse Book of... anthologies included. These are excellent stories about a group of pets that defend their neighborhood against the supernatural that are thrilling, emotional and a bit scary at times. The art is some of the best of Thompson's career. The miniseries made my Best of 2009 list.
Also from Dark Horse: The Life and Times of Martha Washington in the Twenty-First Century, a massive (600+ pages!) collection of every Martha Washington story by Frank Miller & Dave Gibbons.
IDW serve up the second collection of Thom Zahler's wonderful Love & Capes, one of the best super-hero romantic comedies ever produced, featuring the run-up to Mark & Abby's wedding. The comics included here also made my Best of 2009 list.
Also from IDW: Fallen Angel Omnibus Vol. 0, a large collection of the entire original DC-published Fallen Angel series by Peter David & David Lopez. About half of these comics have never been collected before.
Airship Entertainment have the ninth volume of the popular Girl Genius series by Phil & Kaja Foglio, in both paperback and hardcover editions.
