For the Walker DynoMax logo I copied two corporate logos and combined them. No overdone effort on my park. The WALKER logo has changed since the 1980s to feature italicized font.
All the DynoMax print material I’ve seen to date use the merging letters and when Dyno is “open” without a fill; I have not seen it with complete outlines like used on 1988-89 racing cars. So, this may have been a race team modified logo.
