I have two issues of this series that i picked up today that the cover doesn’t match. I realize that issues of the series were released with a couple of different restaurant names on them that sold Bob’s Big Boy. The ones in the core have Elias Brothers restaurant covers. The ones I got say Bob’s Big Boy. The two issues are #331 & #342. Here are photos of the covers.
I have been adding and finding all these different editions. So cool to find one we don’t have yet 
. Added! Thank you for posting!
