Tip Top Weekly, two consecutive issues. Pulp magazines from the dime novel era.
#149 Frank Merriwell's Chance; or, To Make or Break February 18, 1899.
#150 Frank Merriwell Wins; or, The Success of "True Blue" February 25, 1899.
Complete with front and back covers which are still lightly attached. Paper is delicate. Both magazines have stamps from a newsstand and used bookseller in Buffalo, New York. I think these may be from the original sale of the magazines when new.
The picture of the magazines together shows them in plastic sleeves; the marker writing and modern inventory stickers are on the sleeves, not the magazines.
