This is GREAT. I've been looking for these for years. Actually, I am interested in any radio/newspaper strip crossover, particularly if they started their life in radio first, like 'Dragnet'.

Anyway, you have one happy camper. Vintage Mark Trail would be on my wish list, along with the Frank Merriwell strip.

For those of you who are interested, Martin Grams recently offered a short run comic book crossover collection, compiling the 2018 team up between Dick Tracy and The Green Hornet. Contemporary comics are usually too modern for my tastes but my love of Dick Tracy won me over and I ordered a copy. It arrived yesterday, and although a tad pricy (shipping to Canada is alway egregious), I highly recommend it, as I do the collection of vintage Shadow strips he was offering a while back. I suppose you could contact him directly about both if you're interested.

Best;
Scott

Hoppy Fans
Here is a link to a complete 1952 Hopalong Cassidy story from the newspaper funnies. I call it "Alias Fancy Frank Sharpe".
I will follow-up with a continuing story (if there is interest), when I finish editing it.

Links to Hopalong Cassidy comics are readily available, but complete newspaper stories are rare, so if you are a Hoppy fan, please enjoy.
