Original Dandy Comic Keyhole Kate Artwork

[Into The Abyss]

Just obtained a piece of DC Thomson comic art by Allan Morley on card from 1949. The panel measures around 9 x 15 ins and is in good condition for 73 years old. And even though it's written on the left-hand margin that it appeared in Dandy issue #411 in ink by the artist on the reverse in pencil it says issue #409. Bit confusing I know but I have subsequently sourced the comic? See pics below.
