I've never really had a hankering for (trying to) collect the School Bulletins, even though I have some odd 'sample' copies.
However, as you just showed, I have had on my low-priority to-do list to at least get all the space-theme related covers. Wonderful illustrations!
Neither did I (as to collecting these) but as you are probably aware, these just kinda fell into my lap.
Thanks again, Jeff !!!
No, just thought you bought them.
These are the only space related overs they printed.
Thanks Jeff, it's renamed.
