That's No Picture Cover!
Some little crafter cut up some Penny Parker dust jackets and pasted the images of Penny onto the covers of these books! Penny Parkers with a dust jacket routinely sell from $20 to $60+ depending on book and condition. The last two volumes can command over $60 and upwards of $100+. Naked books, maybe a few dollars. Naked books with pasted on cutouts? $12.84.
