This very rare collection of 7 prints were issued in the early 1990's and were sent to Mack Dealer showrooms as a form of advertising with the Mack Bulldog prominently featured in every print. The prints are 16x24 inches and are NOT cardboard! They have been reprinted from the originals on high gloss heavy photographic paper and then backed by 3/8 inch dense foamcore for easy shipping, handling and mounting. Unusual and beautiful, this particular one is titled "Engines So Advanced, They're Pulling A Whole Industry Forward". These have not been seen before and it is likely that most Mack dealer showrooms disposed of them shortly after receiving them because, in their original format, it would have been difficult to mount them on a wall professionally. Ships without the watermark.
