From Wikipedia:
Here Come the ABCs is the second children’s album and eleventh studio album by alternative rock band They Might Be Giants, aimed at young children learning the alphabet.
The bichromatic letters A B C and S are from Octagon, a prismatic design first shown as wood type by Edwin Allen in George Nesbitt’s 1838 First Premium Wood Types Cut by Machinery. The rest of the title and the band name are in Ziggurat, featuring roman caps and italic lowercase characters. Supporting text is set in Geometric 415, Bitstream’s digitization of Metro No. 2.
