Answer: PSALM BOOK

One side has images of chicken fingers, the Legion of Super-Heroes heroine XS, Luke Skywalker, and James Michener's Texas. The other has a WristStrong bracelet, Roman numeral math that yields 1000 (M), a daisy, and the Kansas album Leftoverture. The background of each are QDATR and SFCVT. The letters that fall between these two strings are REBUS. For each pair of images in the same place, they have something that's connected to both of them.

This works like a rebus: PALM containing S + BO + OK. That spells PSALM BOOK.
