In his Lio strip of February 23, 2016, Mark Tatulli pays tribute to Jack Elrod, the second artist of Mark Trail. Creator Ed Dodd wrote and drew the strip from 1946 to 1978 before handing it over the Elrod. Elrod continued with Mark Trail until he retired in 2014.
Tatulli's tribute is uniquely Lio-esque, as it breaks the barriers between comic strips. It's a recurring theme with Tatulli and one that works quite well here.
Of course, Mark Trail now has a new artist -- James Allen -- who I think has done a great deal to revitalize the strip. Perhaps Mark Trail would have a different reaction to mice, now.
