Gwandanaland Comics #564

Published by Gwandanaland Comics in 2017, this collection gathers the complete Rocky X of the Rocketeers series from Lev Gleason's Boy Comics under one cover. The reproduced cover art plunges readers straight into "Horror on Kallaxyn," where Rocky and his companions face down a pair of massive, roaring dinosaur-like creatures while rocket ships streak overhead and word balloons crackle with urgent alien dialogue. It's a terrific showcase of golden-age sci-fi adventure at its most pulpy and fun, delivering the full run of Rocky's outer-space exploits in a single volume.
