@androidarts@mastodon.gamedev.place Eugen Semitjov! They had his book Rymdtecknaren at my primary school library, and I kept checking it out over and over. Later realized my father had subscribed to the magazine that Semitjov wrote and illustrated for (Teknikens Värld) around the time of the space race, and got him the book, then back on my shelf after he passed. Great stuff!
