Jumbo Comics 13

The 8D price on this is an overprint of 6D. I think it was likely a last minute price increase. I've only seen 6d editions of #1-11 of this series, and every issue from 14 up appears in an 8d edition (as well as a UK market 6d version for #24-38). If I ever find a #12, I'm betting it will have a 6d price.
