D-X pump sign collection from the 1960s

this covers all but one of my D-X gas pump signs from the 60s, the one thats not posted here is my tin "D-X super boron" . Probably the most unique is pict#3 which looks to be a "super boron" tin sign but its not. This is a plastic embossed or 3D pump sign. A very rare sign for obvious reasons, the plastic just didnt stand up to the change in temperatures and the combined punishment from the customers,attendants, & the gas hose constently slapping against it.The only reason i have a couple of these left is because they were never installed.
