i want to extend a big thank you to Firstfrog for the incredible content of the April Mystery Box. I am still sorting through the contents.

many US covers, Us First Day Covers, classic US stamps, few classic Canadian, odds and ends of supplier, catalogues and albums.

here is just a small sample of what 8 found so far.

again, many thanks for the chance to participate and win.
