I have known weakness and affection for the superhero school supplies created by Alco in the mid 1970s. So I was overjoyed to find this recently at a toy show, a Batman slide rule that I had no idea existed.
Now my mind races if Batman was the only character in the line of slide rules, seeing as Alco used characters like Shazam and Superman for other merchandise. Is there an Aquaman or Wonder Woman slide rule? Am I seriously contemplating collecting them all?
