The ALA has done "READ" posters with the Twilight series cast for the past couple of years, having issued one for Twilight with Robert Pattinson and Kristen Stewart as "Edward and Bella" and one for The Twilight Saga: New Moon with Taylor Lautner as "Jacob Black."
Additionally, Dakota Fanning appeared in an ALA "READ" poster a few years back for Charlotte's Web.
The new Eclipse poster can be purchased here.
The posters are intended to encourage readership among fans of the respective series encapsulated by them, and it seems that whether "challenged" or not, the ALA regards the Twilight series as a viable tool for their campaign.
