I found this on ebay the same night. A great Maldoff Batman cover.

I didn't stop there. I bid on a few books in the minor hour of the Mycomicshop weekly auction, and stumbled upon some really good deals. At mycomicshop.com auctions there doesn't seems to be much bidding or intereset in a lot of the Golden Age. But Shhhhh! Don't tell anyone else.
I bought Red Ryder #10 9.4 ow, highest graded. and compared to what I spent already it was a drop in the bucket. Ended up with a strange mix
Sensation #44 5.0
Strange Advetnures #15 8.5 ow
Strange Adventures #64 6.5 cow (strangely the 2nd highest graded)
Popular Comics #78 9.0 ow
World's Finest #10 7.0
World's Finest #68 6.0 (also strangely the 2nd highest graded, listed as scarce in OS, no idea if it's true)
I guess you would call it a binge
