It has to be cloth tape. French made Velox or their trade name Tressostar. Quite inexpensive and comes in the major colours; red, white, blue, black - you may find some others. Black would suit your frame. Cloth is what it would have had when it was new probably. Cork is nice but gives a bulky look to the bars. If you need more comfort, double wrap the cloth where you need it (like a carbon fibre frame ! ).
By the way, for a classic bike originality is next to godliness. It has plenty of paint on and the original transfers so leave the work of the Master intact. Just give it a good clean and tidy up. You cannot put originality back after you have removed it.
