What a great pair of vintage Bulldog cuff links with Mack written on the collars! Mack standing for the Mack trucks which used the English Bulldog as their mascot and appeared on the hood of their trucks. This pair of cuff links are from the 60's or 70's and probably had a lot wear as the gold tone on the front edging has been mostly rubbed off and they appear to be silver tone in the pictures. The bulldog's appear to be silver tone and I don't think they were ever a gold tone. The backing is gold tone and they are in fine working order with normal signs of wear and usage. The bulldog in the front is hefty, well defined and easily recognizable and stand out from the black piece of resin plastic they are attached to. Oval in shape they are 1" long and 3/4" wide. Great pair of cuff links for the Mack operator or bulldog lover or both!
