Art, this whole issue arose when one day I found one of Pat Covert's model, a 1962 Impala he called bubbles, which was part of his book on building models cars and where he talks about getting dry transfers professionally printed.
The cost of both dry transfers and decals done professionally is prohibitive. I decided to have a decal sheet printed that not only I can use but that others, if their interested can use too, and then help with the cost.
And Harry is right, these are professionally printed the likes of what comes in kits, which is why it's so expensive, and if I told you the cost, you'd have to hear it sitting down! LOL!
