A tail dragger aircraft pilot reported an incursion on ryn runway 15/33 as he was taxiing to the end...

Narrative:

I had completed by run-up and was taxiing on taxiway bravo toward hold short line for runway 33/15. The taxiway ends at runway 33/15 and the beginning of runway 6R begins at runway 15/33. Ground called and asked if I was done with my run-up. I said yes and he told me to taxi to runway 6R; contact tower and hold short of hold short line. Since I was near or on top of runway 33/15 hold short line I interpreted his instructions to hold short of runway 6R hold short line. When I called tower they advised I had taxied through the runway 33/15 hold short line without approval. I had not been to this airport in several years and the runway marking have; I think; changed since my last visit. Compounding the problem was I was in a tail wheel aircraft and; although I knew it was there; I could not see the runway 33/15 hold short line when the instructions were given. I think some of the problem comes from having two hold short lines in close proximity to each other.
