At work we pulled a set of 1970's stats from our Scooby-Doo shelves last week. And we plan to reprint some of the material in our pocket books later this year.
Now, the style of artwork looks familar to me.
Could this be Dan Spiegle? Maybe working together with another artist?
And does anybody know who wrote Scooby-Doo during the 70's?
If we can get the right credits we'd love to print the names of the creators in our books.
Update 1: Just found out that this story was printed in Scooby Doo Mystery comics #19 and one of the other stories we have picked was taken from #30. We still don't know where the other two stories we have found were first published. (One about the treasure of Sierra Fantasma and one about a ghost on a river boat.) And the Grand Comics Database gives no credits for these issues.
Update 2: Thanks to Mark Evanier who could confirm that Dan Spiegle indees was the artist behind this story! :)
