Thanks Dick. I've attached two more photos of the Dynalube can showing the back label and seam side of the can. Seam appears to be crimped. I have no other photos of the Special can, but I believe all of their cans from this era were laid out the same. I have a repro Sunoco Sun-Motor 1957 can from the Fill-Er-Up website, and its layout is similar, although the back label wording is different from the Dynalube can's. Side opposite the seam (6 o'clock) looks just like the seam side minus the seam itself, i.e. plain color field with no text. Since some of the wording will be the same as the Sun Motor can, I can help you with that if necessary. Hope this helps you out. I appreciate all your efforts with this.
Thanks Again,
Dave
